POLYMER/CONDUCTIVE FILLER COMPOSITE WITH HIGH ELECTRICAL CONDUCTIVITY AND THE PREPARATION METHOD THEREOF

摘要

PURPOSE: An electroconductive composite of polymer/filler is provided to have excellent electrical properties like electric conductivity, while having excellent static electricity dispersion, thereby capable of being used for a vehicle and various electrical and electronic components. CONSTITUTION: An electroconductive composite of polymer/filler comprises polycarbonate, a copolymer of poly(acrylonitrile-butadiene-styrene), maleic anhydride-grafted styrene acrylonitrile copolymer, and carbon nanotubes. The weight ratio of the polycarbonate and the poly(acrylonitrile-butadiene-styrene) is 4:6-6:4. Based on 100.0 parts by weight of a mixture of the polycarbonate and the copolymer of poly(acrylonitrile-butadiene-styrene), a comprised amount of the maleic anhydride-grafted styrene acrylonitrile copolymer is 1-10 parts by weight and a comprised amount of the carbon nanotubes is 0.1-15 parts by weight.
