Abstract
A method of manufacturing a near-infrared ray shielding film is disclosed. The method comprises: providing a raw material of PET; providing tungsten oxides-containing nanoparticles; blending the raw material of PET and the tungsten oxides-containing nanoparticles to obtain a polyester mixture with 80-99.99 wt % of the raw material of PET and 0.01-20 wt % of the tungsten oxides-containing nanoparticles; rolling the polyester mixture to obtain a polyester sheet; and biaxially-orientating the polyester sheet with a orientating rate of 1-100 meters per minute at 60-300° C.
