Abstract:
A device as for transmitting electrical energy or electrical signals comprising a core, an outer conductor and a dielectric material with an intrinsic breakdown threshold between said core and said outer conductor, wherein said dielectric material comprises, at least in part, a material that is insulative in an electric field below a particular threshold and conductive in an electric field exceeding said particular threshold, and the configuration of said core and said outer conductor is such that an external electric field threshold, for which said dielectric material becomes conductive, is significantly less than said intrinsic breakdown threshold of said dielectric material and wherein said dielectric material is an organic material comprising a self-doped copolymer selected from the group consisting of: a copolymer of N-phenyl p-phenylene diamine and an aminonaphthalene sulfonic acid, a copolymer of aniline and an amino-naphthalene sulfonic acid, a copolymer of aniline and 3-(3-aminobenzyloxy)-1-propane sulfonic acid, a copolymer of aniline and 3-(2-aminophenoxy)-1-propane sulfonic acid, a copolymer of aniline and 4-(2-aminophenoxy)-1-butane sulfonic acid, a copolymer of aniline and 1-amino 2,6-bis (4-sulfobutoxy) benzene, and mixtures thereof.
