▎ 摘　　要

NOVELTY - Graphene conductive coating comprises 45-60 wt.% aqueous polyurethane dispersion, 20-24 wt.% modified graphene polyaniline composite, 0.5-3.0 wt.% dispersing agent, 0.11.0 wt.% defoaming agent, 1.0-5.0 wt.% anti-adhesive agent, and rest is deionized water, where the graphene conductive coating is prepared by mixing the peanut shell, melamine and 0.8-1.5mol/L sodium hydroxide solution according to the mass ratio of 1-1.3:1.0-1.5:50, then making a uniform slurry, then diluting with water to 2-3 times, stirring. The bottom layer precipitate is discarded to obtain a biomass dispersion. The biomass dispersion is mixed with the graphene oxide solution to obtain a reaction liquid, is hydrothermally reacted at 15-18 degrees C at 180-200 degrees C, and a modified graphene dispersion by dialysis treatment is obtained, where the content of biomass in the reaction solution is 3.0-4.0 mg/mL, and the content of graphene oxide in the reaction solution is 0.5-2.0 mg/mL. USE - Graphene conductive coating used for protecting film. ADVANTAGE - The graphene conductive coating has excellent storage stability and good electrical conductivity to prepare a graphene conductive film having uniform thickness and uniform conductivity of the paint film. DETAILED DESCRIPTION - The aniline in a graphene dispersion is polymerized to obtain graphene conductive coating. An INDEPENDENT CLAIM is included for a method for preparing a graphene conductive coating, which involves uniformly mixing an aqueous polyurethane dispersion, a modified graphene polyaniline composite, a dispersing agent, an antifoaming agent, a releasing agent and deionized water to prepare a graphene conductive coating.
