Conductive plastic is a functional polymer material that mixes resin and conductive substances and is processed using plastic processing methods. Primarily applied in the fields of electronics, integrated circuit packaging, electromagnetic wave shielding, etc.

Some conductive plastics are classified according to their electrical function, while others are classified according to their production methods. How many are classified according to their production methods? Let's take a look.

According to the production methods of conductive plastics, they can be classified into structural conductive plastics and composite conductive plastics. Structural conductive plastics, also known as intrinsic conductive plastics, refer to plastics that have inherent conductivity or have conductivity after chemical modification. The main conductive materials for structured polymers include:

(1) Metal chelates: such as polyketophthalocyanine;

(2) Charge mobile polymer complexes, such as polycation and CQ complexes.

(3) π - conjugated polymers, such as polyacetylene, (Sr) n, linear polystyrene, layered polymers, etc;

The production cost and process difficulty of this type of polymer materials are high, and there has not been a large-scale production yet. The widely used conductive polymer materials are generally composite polymer materials.

The filling materials of conductive plastics mainly include:

a. Metal dispersion system; b. Carbon black series; c. Organic complex dispersion system.

2. According to different uses, it can be classified into anti-static data, conductive data, and electromagnetic wave shielding data.

3. According to the classification of electrical functions, it can be divided into: insulators, anti-static materials, conductors, and high conductors. Insulators with a general resistance value above 1010 Ω· cm are called insulators; A semiconductor or anti-static material with a resistance value within the range of 104 to 108 Ω· cm; A conductive body with a resistance value below 105 Ω· cm; A high conductor has a resistance value below 100 Ω· cm or even lower.
