Patent ID: 8357858

Claim:
An electrically conductive, thermosetting elastomeric composition, the composition comprising: an initially substantially non-electrically conductive, silicone-based thermosetting base polymer; a particulate filler comprising electrically conductive particles; and an electrically conductive polymer additive; wherein the non-electrically conductive, thermosetting base polymer, the particulate filler and the electrically conductive polymer additive are mixed; wherein the electrically conductive polymer additive comprises one or more of: ethylenedioxythiophene (EDOT); poly(3,4-ethylenedioxythiophene) (PEDOT); PEDOT doped with poly(styrenesulfonate) (PEDOT/PSS); polyaniline; poly(pyrrole); poly(acetylene); poly(thiophene); poly(p-phenylene sulfide); poly(para-phenylene vinylene) (PPV); polyindole; polypyrene; polycarbazole; polyazulene; polyazepine; and polynaphthalene; wherein the weight ratio of the non-electrically conductive thermosetting base polymer to the electrically conductive polymer additive is in a range of 0.5:1 to 1.5:1.
