The Importance of Conductive Coating
Conductive paint is paint coated on a non-conductive substrate and has a specific ability to conduct current and dissipate charges. It is widely used in the modern electronics industry. The conductive ability of the conductive coating can also be used to convert electrical energy into thermal energy for heating residential, industrial and agricultural buildings. In addition, conductive coatings can be used for anti-static, dissipate static electricity and insulation shielding. Moreover, the development of electromagnetic shielding coatings based on conductive coatings is also a significant work.
Accelerate Research and Practice of Graphene in Conductive Coating
According to the different conductive mechanisms, conductive coatings can be divided into intrinsic and filled types. The typical representatives are polyphenylamide type coatings and graphene-filled coatings. Traditional conductive coatings achieve the purpose of coating film conductivity by adding conductive substances as additives. Conductive additives are usually metal or metal oxide particles (such as silver powder, copper powder and zinc oxide). The conjugated structure of graphene gives it high electron mobility and excellent electrical properties. Compared with metal or metal oxide particles, graphene not only has good electrical conductivity, but also has excellent mechanical and thermal properties, making it an excellent conductive coating additive. Graphene has both good electrical conductivity and anti-corrosion properties, so it has a good application effect in static conductive coatings. The surface resistance of the electrostatic conductive paint with graphene is usually between 106 and 109, which can effectively prevent electrostatic conduction.
