Our country has successfully
developed nano interface material that has reached advanced
world levels.
A Xinhua News Agency dispatched from Beijing on
Sep. 27 (reporter ZhaoMingliang BingLi) the surface of building
materials which have been finished have effects of self-cleaning,
fog proof and frost proof. Textile processed with this technology
has functions of waterproof and oil proof. and the clothing
of oil worker is no more full with oil mark …… Institute
of Chemistry of CAS (Chinese Academy of Sciences) declares here
today that after many years of study with great concentration
our scientists get good achievement again on the research about
nano material: the group led by researcher JiangLei in Institute
of Chemistry of CAS not only firstly put forward the structural
theory of the Binary Coordinated Nano Material, but also develop
a series of nano interface material with fantastic function.
Nanometer is a kind of measure, equals to billionth.
Matter in nanometer size has many unusual characteristics. When
nano technology comes into the world it is identified and favored
by scientist around the world. The development of nano technology
comes to research in every field rapidly. Surface and surface
science of nanometer have developed in full flourish in recent
years.
In research of these years, the group of JiangLei,
who is the chief scientist assistant of national subject group
of “nano material and nano structure” and doctor
of Institute of Chemistry of CAS, have found that if make two
kinds of incompatible materials to nano measure, they will have
coordinated interaction under specified conditions and show
special property in macro scope. “Binary coordinated nano
interface material ” namely means processing specially
to the material surface to set up a binary coordinated nano
interface structure in material macroscopic surface so as to
make the material have particular property.
Using this research result, scientists have developed
a kind of interface substance material with both super hydrophile
and super lipophilic. Surface of glass and building material
decorated with this material have functions such as self-cleaning,
fog proof etc.
Researchers also have developed a kind of interface
substance material with both super hydrophoby and super oleophobic.
Textile decorated with this material has functions of waterproof
and oil proof. At present, scientists have successfully applied
these nano interface materials in fields of dress and building
material etc.
Chinese Commodity Transaction Center and Institute
of Chemistry of CAS have already jointly founded a company in
order to accelerate industrialization of the scientific payoffs.

Binary Coordinated Nano
Interface Material
(Abstract) Offered by JiangLei in The Chinese
Academy of Engineering speech,“The Third Period Engineering
Science and Technology Forum……‘Nanometer Material
& Technology’Seminar” of Institute of Chemistry
of CAS
People have common understanding on surface and
interface science at present stage. There can form various interface
between different matters, such as metal, inorganic, organic,
semi conductor and biomaterial interface. Research found that
many important phenomena. With the aid of fantastic functions
and features of surface and interface, which generated by contact
and amalgamation of different materials, create newly typed
materials and parts. That has become the guiding ideology in
many research fields.
In the eyes of physical opinion, surface phase
of condensed state matter has symmetry and free energy, which
is different from bulk phase. When matter is reduced from the
macroscopic size to microscopic size the influence of surface
phase to material physical property will not be allowed to neglect.
Hence, the design and control of surface phase must be the key
point for researching newly typed interface materials.
The new concept “Binary Coordinated Nano
Interface Material” is different from traditional single
bulk phase material. It is to build binary coordinated nano
interface structure on the macroscopic surface of the material.
Design philosophy of the interface material is that people do
not always seek for composing bran-new bulk phase material.
After adopting certain special surface to process, can form
greatly farraginous two dimensional surface phase fields with
two different characters in microscopic size. and the area of
every phase field and “interface” built by two phase
is nanometer size. Research showed that nano phase with different
even completely opposite physical and chemical property under
certain condition was of cooperated counter action so that there
presented transnormal interface physical property on macroscopic
surface, namely binary coordinated nano interface material.
To the knowledge of duality in material world
our ancestors had already realized to utilize logic thought
of Yin and Yang duality. The development of modern science has
also proved that material world from the beginning of least
unit is composed by various coordinated counter duality basic
particles. Not only the composition of matter but also the property
of matter reflects binary cooperativity whenever possible. People
are consciously utilizing the binary cooperativity to research
and make new material. In the aspect of molecule and super molecular
material, such as surface active agent (contemporarily having
hydrophile and water repellent molecule), organic non linearity
optical material (contemporarily having functional molecule
with separative push-draw electronic gene). In organic super
conductor and organic strong magnet, also utilizing compound
molecule crystal generated by charge transfer salt, which is
composed of electron donor and electron acceptor, etc. All shows
the important guiding function of binary coordinated thought
to research and make newly typed materials.
“Binary Coordinated Nano Interface Material”
does its best to popularize binary cooperativity to the interface
with nano size and peruse newly typed interface physical property.
Binary coordinated complementarity of physical property is a
general conception. As it is known it can present many forms.
For example, hydrophile and hydrophobicity (lipophilicity and
oleophbicity), admittance and insulativity, oxidability and
reducibility, complementarity of surface geometry, stable structure
and metastable structure, paramagnetism and anti magnetism,
Type P and Type N of semi conductor, strong conductive body
and anti strong conductive body, laevogyrate and dextrogyrate,
etc. In general situation, the surface phase and interface phase
of bulk material often show one kind of single character. However,
utilizing design philosophy of binary coordinated interface
material after forming binary coordinated interface in microscopic
even in nano size, such interface always shows transnormal interface
physical property. In order to realize the above-mentioned binary
cooperativity it need to be in virtue of soft condensed state
physical and chemical ultimatum to finish the molecule design
of interface material.
1. Physical property material of super biparental
interface (surface with super hydrophile and super lipophilicity)
Study shows light irradiation can cause TiO2 surface
forming binary coordinated nano interface structure with two
concomitant phases of hydrophile and lipophilicity in the nanometer
area. Like that, there will appear magic super biparental character
on the surface of macroscopical TiO2. New material
made by utilizing the principle can decorate the surface of
glass and building material to make them have self-cleaning
and antifogging functions. The biparental binary coordinated
principle can guide the design and invention of super biparental
finishing agent used on other base materials further. For example,
the finishing agent used on fibre and clothes make them have
super biparental property. We can assume washing clothes only
with water instead of traditional abluent; it also can be used
on surface finishing of artificial vas and human organ to prevent
thrombus, and improve the compatibility with living organization,
so as to realize prolonging the service life. Above materials
are very important to people’s life and purifying environment.
2. Physical property material of super dual distant
interface (surface with super hydrophoby and oleophobic)
Utilizing the nano chemical method of epitaxial growth from
downside to upside, from atom to molecule, from main molecule
to congeries, can build interface structure of nano size and
complementary geometry figure (such as alternating with protruding
and concave) on specified surface. As on the concave surface
of nano size, the absorbed gas molecules can exist stably, so
there is a stable gas film on the macroscopical surface, which
makes oil or water cannot contact the surface of material directly,
and makes the surface present transnormal super dual distant
character. At that time the contact angle of water drop or oil
drop with interface tends to max. If coating the surface-finishing
agent made by the material having function of preventing static
on the inside wall of oil pipeline, no touch transport of oil
and pipe wall can be actualized. It has very important value
to the safe course of oil pipeline. Obviously, the super dual
distant character has a broad application foreground in the
area of textile and packaging industry.
3. High efficient photocatalytic interface material
with two phases, namely light anode and light cathode of concomitant
in nanometer size
In virtue of research thinking of photochemistry
and photoelectrochemistry, utilizing nano chemical method plan
to develop manifold nano interface material with photochemistry
activity. For example, binary coordinated interface structure
with concomitant light anode and light cathode can be constructed
in the nano area of TiO2 surface, which has high
efficient photocatalytic effect under the ultraviolet radiation.
It can be used for decomposing poisonous gas (such as formaldehyde,
benzene and nitrogen oxide etc.) and killing the bacteria that
contact its surface. The material will be importantly applied
in air purification and sterilization.
The above-mentioned examples are just three typical
enumerations. But duality in material world is inexhaustible.
Binary coordinated nano interface material will also be inexhaustible
permutation and combination. The world waited for us will be
a rich and colorful, newly typed, high-grade functional material
new world.
Design & Research of
Binary Coordinated Nano Interface Material
1. Background and significance of research
Recently, surface and interface technology of
nanometer level has developed prosperously. Though some new
science pattern is under foundation, they have provided favorable
opportunity for rising intersectional research of such important
subjects as Physics, Chemistry, Biology, Material Science and
Nanometer Technology. " Binary coordinated nanometer interface
material" is a brand new subject of this level, which has
bearing on advanced functioning material research. So far, people
has gained a common sense on surface and interface technology
that various interface can be formed between different materials,
for instance, many momentous discoveries occurs in the research
on metal, inorganic, organic, semiconductor and biologic materials.
In 20 years only, to create new material and apparatus by dint
of surface and interface functioning speciality resulting from
contact and amalgamation of heterogeneity materials has become
the rudder of a lot of research field.
By physical concept, surface phase of condensed
state matter possess symmetry speciality and natural energy
that are quite different from their appearance. When some substance
minishes from macroscopical size to microcosmic size,the impact
of surface comparative material speciality can not be neglected.
Therefore, the design and control of surface appearance is the
key to new interface material research. The new concept ---
"Binary coordinated nanometer interface material"
take coordinated effect of non-balance state resulted from the
good use of chemistry of higher level than molecule and outfields
(photic field, electric field, magnetic field, thermic field,
etc.) as premise, then it constructs binary coordinated nanometer
interface structure on the microscopical surface of materials.
The purpose is seeking new interface materials that possess
technique prospect. The design lemma of this interface material
lies on that people don't pursue compound new materials all
the time. After some special processing of surface, interlaced
planar surface sections of two different substances will be
formed under microcosmic size. Area of each section and the
interface formed by two sections are measured in nanometer.
It is reported that these nanometer sections, which owns different
or even entirely contrary property, may carry on coordinated
interaction under some circumstance, so as to create one kind
of transnormal interface material on microscopical surface,
i.e. " Binary coordinated nanometer interface material
".
It is a brand new subject to form the binary coordinated
surface appearance of this special nanometer interface structure,
and to carry on microcosmic machanism research that shows transnormal
macroscopical physical property. The interaction between different
sections may influence coupling among sections. This coupling
will promote coordinated effect of two sections. Therefore,
it is significant to research transformation and Chemical interact
due to the function of outfield, research the energy transport
and electron transfer between coordinated two phases on the
different exterior phase section of planar surface and research
relative interface Physics and interface Chemistry.
On the other hand, viewing from development of
macroscopical subjects and high-tech industrialization, the
new science and technology stratagem nowadays is not only the
grading developing pattern that separates basic research, technique
exploitation and market-oriented production. Some far-sighted
high-tech leaders and organizers have intended to establish
basic research stratagem to cover technique developing and new
products developing stage, in order to advance techniques and
accelerate the realization of production of new techniques.
For example, in Europe and America, especial in Japan, abundant
experience has been accumulated form the rapid development of
semiconductor material and electronic industry. Similarly, some
developing countries has benefited from the inosculation of
basic research and production of new techniques.
Research plan of " Binary coordinated nanometer
interface material " is base on the developing pattern
that is with high superposition basic research and production
of new techniques, in order to establish rapidly the leading
position of advanced materials on international market. According
to the latest report of author, transnormal surface can be created
from the surface of various original materials by use of aforementioned
basic research fruit. For example, to decorate the surface of
glass and construction materials will add self-cleaning and
mist-repellent, ice/frost-repellent function to the; we can
also add lubrication and reduce friction resistance surface
function on metal materials; similarly,this technique can be
carried on efficient photic/electric catalyze and wave-absorbing
materials.
New products which are manufactured according
to the design principle of binary coordinated nanometer interface
structure, are not only in favor of those technical improvement
and replacement of products among civilian enterprise, such
as architectural industry, automobile and exactitude mechanism
industry,textile industry, communication sense and electronic
industry, biomedicine project and Medical treatment appliance
industry, but also in favor of development of modern military
equipment
2.The design and invention
of binary coordinated nano interface material
About the knowledge to the duality of material
world, our ancestors had wakened up to logic thinking of using
yin and yang duality early. Modern scientific development also
approves, from the smallest unit, material world is made up
of basic particles with duality that can cooperate and complement
each other. Not only material buildup but also material characters
can reflect the character of binary coordinated all the time
and all the where. People are studying new material with the
character of binary coordinated consciously. For example, there
is surfactant (a kind of molecule that has hydrophile and discharging
group at the same time) in the side of molecule and supermolecule
material; there is also organic nonlinear optic material (A
kind of functional molecules that has detached pushing and pulling
electron group); in the side of organic superconduct and organic
iron magnet, complex molecular crystal generated by charge-transfer
compound made up of electron donor and electron acceptor is
utilized etc., which show that the thought of binary coordinated
has important guiding function for developing new materials.
Under the sustain of CAS knowledge innovative
project, centering on the design and study thought of above
binary coordinated nano functional interface material, the research
team of functional interface material in Institute of Chemistry
of CAS which present the author is belonged to studies on the
following three kinds of materials and gets important improvement.
1. Physical property material of super biparental
interface (surface with super hydrophile and super lipophilicity)
Study shows light irradiation can cause TiO2
surface forming binary coordinated nano interface structure
with two concomitant phases of hydrophile and lipophilicity
in the nanometer area. Like that, there will appear magic super
biparental character on the surface of macroscopical TiO2.
New material made by utilizing the principle can decorate the
surface of glass and building material to make them have self-cleaning
and antifogging functions. The biparental binary coordinated
principle can guide the design and invention of super biparental
finishing agent used on other base materials further. For example,
the finishing agent used on fibre and clothes make them have
super biparental property. We can assume washing clothes only
with water instead of traditional abluent; it also can be used
on surface finishing of artificial vas and human organ to prevent
thrombus, and improve the compatibility with living organization,
so as to realize prolonging the service life. Above materials
are very important to people’s life and purifying environment.
2. Physical property material of super dual distant
interface (surface with super hydrophoby and oleophobic)
Utilizing the nano chemical method of epitaxial
growth from downside to upside, from atom to molecule, from
main molecule to congeries, can build interface structure of
nano size and complementary geometry figure (such as alternating
with protruding and concave) on specified surface. As on the
concave surface of nano size, the absorbed gas molecules can
exist stably, so there is a stable gas film on the macroscopical
surface, which makes oil or water cannot contact the surface
of material directly, and makes the surface present transnormal
super dual distant character. At that time the contact angle
of water drop or oil drop with interface tends to max. If coating
the surface-finishing agent made by the material having function
of preventing static on the inside wall of oil pipeline, no
touch transport of oil and pipe wall can be actualized. It has
very important value to the safe course of oil pipeline. Obviously,
the super dual distant character has a broad application foreground
in the area of textile and packaging industry.
3. High efficient photocatalytic interface material
with two phases, namely light anode and light cathode of concomitant
in nanometer size
In virtue of research thinking of photochemistry
and photoelectrochemistry, utilizing nano chemical method plan
to develop manifold nano interface material with photochemistry
activity. For example, binary coordinated interface structure
with concomitant light anode and light cathode can be constructed
in the nano area of TiO2 surface, which has high efficient photocatalytic
effect under the ultraviolet radiation. It can be used for decomposing
poisonous gas (such as formaldehyde, benzene and nitrogen oxide
etc.) and killing the bacteria that contact its surface. The
material will be importantly applied in air purification and
sterilization.
3.Conclusion

of binary coordinated nano interface material studied by the
author’s research team recently. In recent years, rapid

as “our ignoring new area”. Chinese Commodity Transaction
Center has invested 20 million yuan to drive its industrialization,
and has attracted several big enterprises to develop the special
industry, and it is hopeful to realize the industrial scale
in one year.
The duality of material world is infinitude, and
binary coordinated nano interface material will be also infinitude
permutation and combination. Along with rapid development of
science, the research about binary coordinated nano interface
material will enter a new developing time, and a new and colorful
world of high grade functional materials will wait for us.
