Commonly used conductive fillers are metal powder and carbon powder. Coatings prepared with metal powder as filler have good conductive properties, but the metal density is high, which is easy to settle in coatings, and easy to oxidize during service, which leads to the decrease of conductive properties or even loss of conductive properties of coatings. Compared with metal fillers, carbon-based conductive fillers have the advantages of low density, corrosion resistance and stable conductivity. Carbon black and graphite are common carbon-based conductive fillers. In recent years, carbon nanotubes (CNTs) and graphene (GNS) as new conductive fillers have achieved remarkable results. In this paper, the conductive mechanism, research status and factors affecting conductive properties of carbon nanotubes and graphene conductive coatings are discussed, and the future research directions are prospected.
