Abstract

The invention provides a PC conductive plastic. The PC conductive plastic comprises the following raw materials in parts by weight: 75-82 parts of a PC material, 2-6 parts of zinc oxide, 8-10 parts of carbon nanotube modified particles and 8-12 parts of ethylene rubber. According to the invention, PC is used as a base material and is mixed with carbon nanotube modified particles and other additives, and the mixture is processed in a plastic processing and forming mode to form a functional polymer material. According to the invention, the huge change from an insulator to a semiconductor to a conductor is realized, and the span of the possible change can be maximized in all substances. Compared with the traditional material, the composite material has the characteristics of light weight, easiness in forming, adjustable resistivity and the like, and can be conveniently synthesized or compounded into materials with various structures through molecular design.
