Porous carbon coated polyaniline composite material, preparation method and application thereof, corn stalk carbon-based paint and coating

The invention provides a porous carbon coated polyaniline composite material, a preparation method and application thereof, a corn stalk carbon-based paint and a coating, and belongs to the technical field of biomass utilization. The polyaniline-loaded porous corn stalk carbon composite material, namely the porous carbon-polyaniline composite material, is prepared on the basis of a corn stalk raw material. Water contact angle and electrochemical alternating current impedance tests show that the porous carbon coated polyaniline composite coating has excellent water solution repulsion performance and relatively high resistance, and has excellent self-cleaning and stain resistance due to the super-hydrophobicity of the porous carbon coated polyaniline composite coating; and Pi-Pi conjugation of polyaniline extending along the main chain of the polymer enables the polyaniline to have high conductivity and redox activity, and shows excellent performance in the aspect of corrosion protection. 本发明提供了一种多孔碳@聚苯胺复合材料及其制
