1. A fuser member consisting of a mixture of a polyimide and an aramid polymer wherein said aramid polymer is in the configuration of fibers, and wherein said aramid fibers are represented by the following formula/structure wherein n represents the number of repeating segments and wherein said fibers have a diameter of from about 1 to about 1,000 microns; wherein said mixture optionally contains a polysiloxane polymer selected from the group consisting of a polyester modified polydimethylsiloxane, a polyether modified polydimethylsiloxane, a polyacrylate modified polydimethylsiloxane, and a polyester polyether modified polydimethylsiloxane; wherein said mixture optionally contains components selected from the group consisting of aluminum nitride, boron nitride, aluminum oxide, graphite, graphene, copper flake, nano diamond, carbon black, carbon nanotube, metal oxides, doped metal oxide, metal flake, conducting polymers, and mixtures thereof, and a polysiloxane; wherein said fuser member optionally includes at least one functional intermediate layer disposed on the polyimide and aramid polymer mixture in the form of a substrate layer and an overcoating layer in contact with the at least one functional layer; wherein said intermediate layer comprises a silicone, a fluoroelastomer or mixtures thereof, and the overcoating layer comprises a fluoropolymer. |
