NOVELTY - Graphene-containing alkenyl composite material-containing weather-resistant paint comprises graphene, where the graphene is modified by pyrene-containing azo compound i.e. 4-((E)-(4-((E)-pyren-1-ylmethyleneamino)phenyl)diazenyl)phenol (I). USE - Used as graphene-containing alkenyl composite material-containing weather-resistant paint. DETAILED DESCRIPTION - Graphene-containing alkenyl composite material-containing weather-resistant paint comprises graphene, where the graphene is modified by pyrene-containing azo compound i.e. 4-((E)-(4-((E)-pyren-1-ylmethyleneamino)phenyl)diazenyl)phenol of formula (I). An INDEPENDENT CLAIM is also included for preparing weather-resistant coating, comprising (i) synthesizing pyrene-containing azo compounds, (ii) ultrasonic dispersing graphene nanosheets and pyrene-containing azo compound in a mass ratio of 1:0.5-2 in absolute ethanol for 1-3 hours, reacting at room temperature for 20-48 hours, filtrating and drying to obtain pyrene azo compound-containing modified graphene composite material, (iii) adding the pyrene azo compound-containing modified graphene composite material into the mixed solution of butyl acetate and propylene glycol methyl ether acetate, and ultrasonically dispersing for 0.5-1 hour, adding polyurethane component A into the graphene-based composite material mixture, stirring for 0.5-1 hour, adding component B curing agent and stirring for 5-20 minutes to obtain final product.
