Abstract
This invention is directed to polyimide films having a carbon nanotube filler to provide a surface resistivity in a range from 50 ohm/square to 1.0.times.10.sup.15 ohms/square. The electrically conductive polyimides of the present invention have an excellent balance of properties relative to conventional polyimides having a conductive filler, due at least in part to the film's water content, degree of imidization and polymer orientation.
