Abstract: Recent research and industrial production of black polyimide film were reviewed, including four classes, insulation, antistatic, electrically conductive, and thermal conductive ones. The frequently used additives, conductive and nonconductive carbon black pigments, inorganic or organic matting agents, and frequently used methods, such as ceramic packing, adopt pretreatment, mixing, and in situ polymerization were discussed. In the end, development trend of the black polyimide films was predicted.

Key words: polyimide, black film, transmittance, glossiness, surface resistivity
