Abstract
The present invention provides a method for manufacturing a polyimide film with a reduced gloss, which comprises providing a diamine and a diacid anhydride for polymerization in a solvent to form a polyimide precursor solution; adding 2-5 equivalents of a dehydrating agent and a catalyst into the polyimide precursor solution and then coating a carrier with the polyimide precursor solution to form a polyimide gel film; providing an embossing wheel to roll the polyimide gel film peeled from the carrier at a temperature of 140-200° C and a pressure of 3-10 Kgf/cmto form a concave and convex shape on a surface of the polyimide gel film; and baking the polyimide gel film to form a polyimide film with a 60° gloss of less than 100 GUs.
