Abstract:
A conducting polymer composite material comprising:a minor phase material comprising a semicrystalline polymer having a crystallinity from greater than 30% to about 80% and having a solubility parameter, .delta..sub.A ;a conductive 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 conductive network in said minor phase material; anda major phase material having a solubility parameter, .delta..sub.B, 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 conductive network in said major phase material, forming a (semi)conductive ternary composite having distinct co-continuous phases which meets the following criteria for immiscibility, 7.gtoreq.(.delta..sub.A --.delta..sub.B).sup.2.gtoreq.0.
