Abstract:
1. An electrically conductive film, comprising: A. a continuous or discontinuous, non-conductive first phase comprising a polyimide base polymer, and B. a discontinuous, conductive second phase comprising 80, 85, 90, 95, 96, 97, 98, 99 or 100 weight percent carbon nanotube particles, wherein the weight percent of the second phase, based upon the total weight of both phases, is in a range between any two of the following percentages: 0.10, 0.20, 0.30, 0.40, 0.50, 0.75, 1.0, 2.0, 3.0, 4.0, 5.0, 10.0, wherein the film has a thickness between eight and 125 microns, wherein the film precursor is oriented on a molecular scale in one or more directions to provide a surface electrical resistivity between, and including, any two of the following 1×10 wherein the film precursor is oriented on a molecular scale in one or more directions to provide a volume electrical resistivity between, and including, any two of the following 1×10 wherein the film has a mechanical elongation in a range between and including any two of the following 50, 60, 70, 75, 80, 85, 90, 95 and 100 percent.
