    • A process of manufacturing a white polyimide film comprising performing condensation polymerization of monomers comprising diamine and dianhydride components to obtain a solution; adding a dehydrant, a catalyst and a coloration filler into the solution to obtain a precursor solution; coating a layer of the precursor solution on a support; and baking the coated layer of the precursor solution to form a white polyimide film. The diamine component can include 2,2′-bis(trifluoromethyl)benzidine, and the dianhydride component can include 3,3′,4,4′-biphenyltetracarboxylic dianhydride and 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride. The coloration filler can include TiO2, Al2O3, CaCO3, CaSO4, SiO2, BN, AlN and clay.

    • A white polyimide film comprises a polyimide base polymer and a coloration filler homogeneously distributed in the white polyimide film by reacting a diamine component with a dianhydride component and a coloration filter. The diamine component can include 2,2′-bis(trifluoromethyl)benzidine, and the dianhydride component can include 3,3′,4,4′-biphenyltetracarboxylic dianhydride and 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride. The coloration filler can include TiO2, Al2O3, CaCO3, CaSO4, SiO2, BN, AlN and clay. The white polyimide film has a coefficient of thermal expansion (CTE) less than about 60 ppm/° C. in a temperature range between about 100° C. and about 200° C. , an elongation rate between about 5% and about 60%, and a b*-value between about 0 and about 15. In some embodiments, a method of manufacturing the white polyimide film is also described.
