Abstract

See full text

A transparent polyester film has low visible light transmittance of 5-50% by JIS K7705 testing standard and a high infrared-blocking rate of at least 90% by JIS R3106 testing standard, which is extruded from a kind of polyester resins obtained from 5-40 wt % of nanoparticle-based thermal insulation slurry and/or 0.005-0.1 wt % of nanoparticle-based black pigment slurry by weight of and to react with the polymerization materials to completely perform an esterification and a polycondensation, wherein the thermal insulation nanoparticle has a chemical formula of CsXNYWO3-ZClC with an average particle size of 10-90 nm and the nanoparticle-based black contains carbon black particles having a particle size of 20-80 nm.
