Polyaniline micelle and graphene composite material, electrode coating, working electrode and preparation method of polyaniline micelle and graphene composite material

The invention discloses a polyaniline micelle and graphene composite material, an electrode coating, a working electrode and a preparation method of the polyaniline micelle and graphene composite material in the technical field of corrosion protection, and solves the problem in the prior art that graphene is easy to agglomerate, polyaniline is difficult to dissolve in water, and excellent properties of the two materials cannot be effectively utilized. The polyaniline micelle and graphene composite material comprises water-based polyvinyl alcohol-polyaniline micelles and graphene. Pi-Pi bonds beneficial to inhibition of graphene agglomeration are formed between the graphene and the water-based polyvinyl alcohol-polyaniline micelles, the water-based polyvinyl alcohol-polyaniline micelles as a component of the composite material enables the composite material to have high conductivity and corrosion resistance of polyaniline, and the problem that polyaniline is difficult to dissolve in water is solved.
