Nano grain size yellow tungsten oxide may be applied for manufacturing thermal insulation paper so that it has the advantages of heat insulation, light insulation, anti-UV, safety and privacy protection. You may know that the part of the solar energy isolated by the glass is the total amount of reflection plus the amount of energy that the glass absorbs and then dissipates outward.
Gasochromic property is also an attracted property of yellow tungsten oxide. A relatively regular porous yellow tungsten oxide film may be obtained by sol-gel method using tungsten hexachloride as a raw material and introducing a suitable amphiphilic polymer template PS-co-PAAL. It is found that the porous structure can increase the diffusion rate of ions and hydrogen atoms and increase the corresponding speed of gaschromism. And it can be seen that the research on gaschromism mainly focuses on the promotion of the diffusion of substances in the process of discoloration.
