A New Strategy of Constructing Mechanical Enhanced and Electrical Conductive Meta-aramid/Polyacrylonitrile Hybrid Fibers

Abstract Proper method for constructing electrical conductive m-aramid fibers without sacrificing its excellent integrated performance is still a challenge. Here a new strategy is utilized to construct electrical conductive PMIA/PAN hybrid fibers. No sensitizers or activators are needed in this method, contrast to traditional electroless plating methods. Specifically, the resulted PMIA/PAN hybrid fibers maintained a high tensile strength of 4.7 cN/dtex. Furthermore, the CuS-coated PMIA/PAN hybrid fibers (PMIA/PAN-CuS) exhibited high conductivity.
