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&#xd7;10ohms/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.

Electrically conductive polyimide compositions having a carbon nanotube filler component and methods relating thereto

A laminate having improved resistance to separation failure when incorporated into a flexible circuit structure. The laminate comprising a highly bondable polyimide and is preferably formed from a polyamic acid comprising a tetracarboxylic acid component, a diamine component, and 0.1 to 5.0 mole % of a dicarboxylic acid component, with respect to the tetracarboxylic acid component, and wherein the adhesive strength of the laminate is greater than 10  N/cm, and more preferably greater than 19 N/cm.
