NOVELTY - Preparing bacterial cellulose/polyaniline/graphene film material, comprises adding acidified graphene into a surfactant, and then dispersing in hydrochloric acid solution, adding aniline monomer, stirring to obtain a mixture A; mixing the oxidizing agent with hydrochloric acid solution, to obtain a mixture B; dropwise adding the mixture B into mixture A, and carrying out in situ oxidation polymerization to obtain polyaniline/graphene composites solution; and vacuum filtering bacterial cellulose pulp, filming, adding polyaniline/graphene composites solution, filming, and drying. USE - The film material is used as electrode in supercapacitor (claimed). ADVANTAGE - The method is suitable for large-scale production, has simple preparation process, and low cost. The film material is stabile and has mechanical properties. DETAILED DESCRIPTION - Preparing bacterial cellulose/polyaniline/graphene film material, comprises (i) cutting bacterial cellulose into pieces, soaking in deionized water, ultrasonically washing, then placing in deionized water, stirring to disperse uniformly, and then transferring into a stirring homogenizer, to obtain bacterial cellulose pulp; (ii) adding acidified graphene into a surfactant, and then dispersing in hydrochloric acid solution to a concentration of 1 mol/l, adding aniline monomer, stirring until graphene is dispersed evenly, to obtain a mixture A; (iii) mixing the oxidizing agent with 1 mol/l hydrochloric acid solution, to obtain a mixture B; dropwise adding the mixture B into mixture A at 0.5-60 drops/second, and carrying out in situ oxidation polymerization to obtain polyaniline/graphene composites solution; and (iv) vacuum filtering bacterial cellulose pulp, filming, adding polyaniline/graphene composites solution, filming, and drying in a vacuum oven; where the mass ratio of bacterial cellulose in bacterial cellulose/ polyaniline/graphene membrane material to aniline monomer is (0.1-6):1; the mass ratio of bacterial cellulose to acidified graphene is 1:(0.03-0.15); and the mass ratio of aniline monomer and oxidizing agent is (0.5-5):1.
