Abstract:
An infrared absorption film includes a polymer resin substrate, a polymer dispersant and an infrared absorption material. The infrared absorption material has a plurality of tungsten oxide and/or composite tungsten oxide nanoparticles dispersed in the polymer resin substrate by the polymer dispersant, wherein a weight ratio of the polymer dispersant to the infrared absorption material is between 0.3 and 0.6.
