Phosphotungstic Acid Applied for Thermal Insulation Film

Phosphotungstic acid is an extremely important raw material for producing a thermal insulation film. For example, it can be used to prepare a photochromic material composed of an inorganic/polymer composite material. And the obtained composite photochromic material can be sprayed on the surface of the automobile window, and then sprayed with a varnish to form a window film. Due to its own environmental protection, such smart film is more and more widely applied in automobiles.

Experts said that this composite photochromic material can be prepared by formulating phosphotungstic acid into 5% polyacid ethanol solution 5-10 parts, and preparing 1% polyvinylpyrrolidone ethanol under stirring up to 100 parts. Besides, the experts also introduced that the obtained heat-insulating film can resist ultraviolet rays with characteristics of heat insulation and anti-glare, so it can improve the comfort of the human body while reducing the UV radiation to drivers’ skin, and ensure the clear vision of the driver. In other words, the driving safety is guaranteed.
