Transparent Thermal Insulation Nano Materials

Nano thermal insulation coating can effectively block infrared and ultraviolet rays in sunlight. When sunlight penetrates the glass and enters the room, it can block more than 99% of ultraviolet rays and block more than 80% of infrared rays. Moreover, its heat insulation effect is very good, can make the indoor temperature difference 3-6˚C, can keep the indoor cool air.

Nano thermal insulation coating is also a very environmentally friendly material, mainly because the coating film does not contain benzene, ketone and other ingredients, nor does it contain other harmful substances. It is truly green and environmentally friendly and meets international environmental quality standards.

There are three transparent Thermal Insulation Nano Materials

1. CS0.33WO3 Cesium-doped tungsten oxide nanoparticles
CS0.33WO3 Cesium-doped tungsten oxide nanoparticles（Cesium tungsten bronze ）transparent nano thermal insulation coating stands out from many transparent thermal insulation coatings due to its environmental friendliness and high thermal insulation characteristics, and currently has the best thermal insulation performance.

2. ITO nanoparticles
Nano-ITO (In2O3-SnO2) has excellent visible light transmittance and infrared blocking characteristics, and is an ideal transparent thermal insulation material. Since indium metal is a scarce metal, it is a strategic resource, and indium raw materials are expensive. Therefore, in the development of transparent heat-insulating ITO nanoparticles coating materials, it is necessary to strengthen process research to reduce the amount of indium used on the premise of ensuring the transparent heat-insulating effect, thereby reducing production costs.

3. Nano ATO
Nano-ATO antimony-doped tin oxide coating is a kind of transparent thermal insulation coating material with good light transmittance and thermal insulation performance. Nano antimony tin oxide (ATO)  has good visible light transmittance and infrared barrier properties, and is an ideal thermal insulation material. The method of adding nano ATO powder antimony to the coating to make a transparent thermal insulation coating can effectively solve the thermal insulation problem of glass. Compared with similar products, it has the advantages of simple process and low cost, and has extremely high application value and broad application.

Nano silver wire is used for transparent conductive film

Characteristics of nano silver wire:

1. Silver nano wire has high specific surface area, electrical conductivity and thermal conductivity.
2. Nano silver wire has surface plasmon effect: Surface plasmon refers to the electron density wave propagating along the metal surface generated by the interaction between freely vibrating electrons and photons that exist on the metal surface.
3. Silver is a good conductor of electricity, with low resistivity and high conductivity. Applying nano-silver wires to the conductive layer will draw out the collected current, which can reduce energy loss compared with TCO semiconductors.
4. If nano silver wires with a particle size smaller than the incident wavelength of visible light are used, the silver wires can be arranged very densely, and this technology can increase the current collecting area of ​​the silver electrode of the solar cell. It does not block the transmission of light, and at the same time, it can fully absorb light energy by taking advantage of the characteristics of light diffraction.

For transparent conductive film applications:
Due to its nanostructure size effect, nano silver wire has the characteristics of good conductivity, excellent light transmittance, flexibility and wide source of raw materials. The flexible TCF prepared with nano silver wires has the advantages of high transparency, low square resistance, good flexibility, low price, simple process, etc., and is considered to be the next generation of new materials in the field of flexible transparent conductive films.
After years of development, the preparation methods of nano silver wire flexible transparent conductive film mainly include spraying method, spin coating method, Meyer rod coating method and screen printing method. According to different manufacturing methods, the addition amount is different.
AgNWs flexible TCF is favored by the optoelectronic industry due to its excellent optical properties, electrical conductivity and flexibility, and is a new direction for industrial development.
In addition to the excellent conductivity of silver, nano-silver wires also have excellent light transmittance and flexibility due to the nano-level size effect, which provides the possibility to realize flexible, bendable LED displays, touch screens, etc., and A lot of research has applied it to thin-film solar cells. In addition, due to the large aspect ratio effect of silver nanowires, it also has outstanding advantages in applications such as conductive adhesives and thermally conductive adhesives.

The length of the nano silver wire produced by our Hongwu Nanomaterials Company is generally greater than 20 microns, and other lengths can also be customized. If you are interested in this, welcome to consult us.
