Abstract:
A conducting polymer composite that is crosslinked, comprising:a minor phase material comprising a semicrystalline polymer having a crystallinity from about 30% to about 80% and having a solubility parameter &dgr;A, in Joules per cubic centimeter; a conducting filler material dispersed in said minor phase material in an amount which is at or just exceeds the percolation threshold and sufficient to generate a continuous conducting network in said minor phase material, and a major phase material having a solubility parameter &dgr;B in Joules per cubic centimeter, said major phase material being a polymer which when mixed with said minor phase material will not engage in electrostatic interactions that promote miscibility, said major phase material having said minor phase material dispersed therein in an amount which is at or just exceeds the percolation threshold and sufficient to generate a continuous conducting network in said major phase material, forming a conducting polymer composite having separate phases which meets the following criteria for immiscibility, 0.30&gE;(&dgr;Aâˆ’&dgr;B)2&gE;0, wherein said major phase of said conducting polymer composite is chemically crosslinked and said minor phase remains substantially uncrosslinked.
