(Summary description)Conductive plastics is a very active research and development field nowadays. It has developed from pure laboratory research to applied research and become a new generation of electronic materials. According to the conductive mechanism, conductive polymer materials can be divided into two types: structural type and composite type.   At present, the synthesis process of structural conductive polymers is complex and the cost is high. Due to its simple processing technology and low cost, composite conductive polymer has been widely used in electronics, automobile, civil and other fields. Structural conductive plastic is a functional polymer material made by mixing resin with conductive material. It is mainly used in electronics, integrated circuit packaging, electromagnetic shielding and other fields.   Conductive plastics can generally be classified into the following two categories:   1, according to the electrical performance classification, can be divided into: insulator, antistatic body, conductive body, high conductor. Resistance is generally greater than 1010 Ω · cm called insulators; Resistance to Ω · cm diameter range of 104 ~ 109 is called semiconductor or antistatic body; Resistance value is less than 104 Ω · cm called conductive body, resistance under 100 Ω · cm called high conductor is even lower.   2. Manufacturing methods of electric plastics can be classified into two types: structural conductive plastics and composite conductive plastics. Structural conductive plastics, also known as intrinsic conductive plastics, refer to the conductivity of their own or their chemical modification.   Structural conductive polymer materials: (1) conjugated polymers: such as polyethylene, (Sr) N, linear polybenzene, layered high polymer, etc. (2) Metal chelates, such as polyketone phthalocyanine; (3) Charge mobile polymer complex: such as polycation, CQ complex. The production cost of polymer structural materials is high, and the technology is difficult, so it has not been produced on a large scale. Currently, conductive polymer materials are widely used as composite polymer materials, and their fillings mainly include: (a) Metal dispersion system; (b) Black carbon; (c) Organic complex dispersion system; (d) Carbon fiber.   3. According to different USES, low-temperature plasma can be divided into: Anti-static materials, conductive materials, electromagnetic shielding materials, tunnel theory explains the impact of conductive packing on conductivity. Conductive plastics conduct electricity because electrons can pass through the gaps between conductive fillers. At a certain concentration, as long as the distance between conductive fillers is reduced by a small part, electrons can conduct electricity through the pores between conductive fillers. At this time, the resistivity will be suddenly changed and the conductive plastic will change from the original insulator to conductor, which will produce leakage effect. The percolation concentration of carbon black filled LDPE compound is closely related to the structure of carbon black. The percolation concentration of the specially conductive carbon black filler compound is lower than that of the acetylene carbon black filler compound. In the production process, it is still difficult to reach the critical concentration, but the adoption of low temperature plasma treatment technology can make it easier to reach the critical concentration.
