With the development of high technology, such as electronic industry, computer industry and energy industry, the social demands for conductive materials is increasing. Molecular conductor is a kind of important conductive material, which has been widely used in the development of many fields due to the advantages of light weight, environmentally friendly and strong designability.

Molecular conductors can be divided into inorganic and polymer conductors.
1. Carbon molecular conductors: carbon molecular conductors mainly include graphite, carbon nanotubes (CNTs), bamboo charcoal and others, which have the advantages of high strength, high elasticity, lubricity and heat resistance and thermal conductivity.
2. Metal oxidation molecular conductors: Metal oxidation molecular conductors mainly include zinc oxide doped with aluminum (ZAO), lanthanum doped with calcium chromate and tin dioxide doped with antimony (ATO). With the advantages of good chemical stability, moderate cost, this type of material is commonly used in industrial automobile production, construction and other fields.
1. Composite polymer molecular conductors: Composite polymer molecular conductors are obtained by dispersion polymerization, lamination composite or filling composite, which includes inorganic and organic composite conductive molecular.
2. Structural polymer molecular conductors: Structural polymer molecular conductor refers to the polymer material which has the conductivity capability due to the ion transition, electron conjugation or doping. With the advantages of corrosion resistance, low density, good conductivity, easy processing, high elasticity, they can be used in the production of computer displays, stealth high-tech materials, solar materials and others.
