POLYIMIDE/CARBON NANOTUBE COMPOSITE FILM AND PREPARATION METHOD THEREFOR

摘要

A polyimide/carbon nanotube composite film consisting of the following components in parts by weight: 150-250 parts of polyimide polymer, 1-2 parts of fullerene, 0.1-0.2 part of rare earth oxide and 2.5-3.5 parts of modifier, the polyimide polymer comprising the following components in weight percent: 0.5-3% of carbon nanotube, 1-3% of titanium dioxide, 0.5-3% of carbon nanotube, 0.1-2% of modified kaolin, 0.1-2% of copper fluorosilicate, and the balance being polyimide.
