a new kind of near infrared absorbent synthesized with tungsten(Ⅵ)chloride and tributyl phosphate are introduced. By mixing this materials into methyl methacrylate (MMA)
a new kind of near infrared plastic filter is prepared. The optical properties and properties of matter were tested. Nature ageing test
accelerated ageing test
thermal resistance ageing test were also carried out. The result indicates that this new kind plastic filter is characterized by high transmittance of visible light and high absorptivity of near infrared
