THERMALLY STABLE CONDUCTING POLYMER COMPOSITES FOR MELT PROCESSING

摘要

One of the main limitations of intrinsically conductive polymers, ICP, is their lack of thermal-oxidative stability. Through in-situ deposition of ICPs onto carbon black substrates, thermal-oxidative stability is improved. It is then possible to incorporate these composites into higher melting resins such as nylon, polycarbonate, and polyester without degradation or conductivity loss in the conducting polymer. The resulting thermoplastic compounds exhibit improved electrical, mechanical, and rheological properties compared to those with unmodified carbon black.
