Tungsten oxide nanoparticles may be used to prepare a new type of heat insulation film for applying to automobiles, which has surface scratch resistance, high heat insulation and UV resistance to shield more than 99% ultraviolet rays, thereby reducing fuel and improving human comfort. And such film has good light transmittance to ensure that the owner's vision is clear.

More importantly, if the car is attached with such a transparent thermal insulating film, and if the car window is unfortunately hit, the film can prevent the broken glass from splashing and hurting people, and can largely protect the passengers in the car from being damaged by the glass. In addition, tungsten oxide glass has excellent optical selective permeability and reflectivity so that it can maximize the transmission of visible light and maximize the reflection of infrared rays. Also, such thermal insulating film does not adopted a metal plating, so the corrosion problem of the metal and the interference problem of the metal plating on the electromagnetic signal are avoided, and the life of the product is prolonged, to provide users with the best experience.
