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.

Abstract: A multilayer polyimide-containing film comprises a coloring layer containing a pigment, and a first protection layer disposed on one surface of the coloring layer, the first protection layer having a thickness between about 0.5 and about 3 micrometers. In some embodiments, methods of manufacturing the multilayer polyimide-containing film are also described.
