      Classification of conductive plastics


      1.1. According to the classification of electrical properties, it can be divided into: insulator, antistatic, conductive and high conductor. Generally, the insulator with a resistance value of more than 1012 Ω· cm is called an insulator; the semiconductor or anti-static body with a resistance value of 105 ~ 1011 Ω· cm is called a semiconductor; the conductor with a resistance value of less than 105 Ω· cm is called a conductor; the high conductor with a resistance value of less than 100 Ω· cm is called a high conductor.


      1.2. According to the manufacturing method of conductive plastics, it can be divided into structural conductive plastics and composite conductive plastics


      1.2.1 structural conductive plastic, also known as intrinsic conductive plastic, refers to the plastic that has conductivity itself or has conductivity after chemical modification. The synthesis process of structural material is complex, high cost, and very expensive at present. It is a kind of conductive plastic with real significance. Once the R & D breaks through the technical bottleneck, it will bring unimaginable impact on our life.

      Structural polymer conductive materials mainly include:


      (1) π - conjugated polymers, such as polyethylene, (SR) n, linear polyphenylene, layered polymers, etc;


      (2) metal chelates: such as polyketo phthalocyanine;


      (3) charge moving polymer complex: such as polycation, CQ complex.


      1.2.2 composite type is composed of conductive material and polymer material. This kind of functional polymer material has been widely used because of its low cost and can meet various molding requirements. According to different conductive fillers, composite conductive plastics can be divided into antistatic agent system, whisker system, metal system (various metal powders, fibers, sheets, etc.), carbon system (carbon black, graphite, etc.), which can be adjusted and produced according to different requirements of product resistance value.


      1.3. It can be divided into:


      Antistatic materials, conductive materials and electromagnetic wave shielding materials.
