Abstract: A black polyimide film includes a polyimide polymer formed by reaction of diamine monomers with dianhydride monomers, and a carbon black having an oxygen-to-carbon weight ratio higher than 11%. The black polyimide film can prevent flaking of carbon black when it is subject to an etching process, and exhibit desirable characteristics of extension rate and insulation.

Abstract: A polyimide film includes a polyimide layer including a polyimide base polymer, and a polyimide powder distributed in the polyimide base polymer, the polyimide powder being obtained by reacting a diamine with a dianhydride at a molar ratio of about 1:0.950 to about 1:0.995. Moreover, the polyimide film may have a multilayered structure including at least a second polyimide layer stacked on a surface of the polyimide layer. The second polyimide can also include the polyimide powder at a weight ratio less than about 20 wt % of the total weight of the second polyimide layer. Embodiments described herein also include methods of preparing the polyimide films.
