NOVELTY - An electrically conductive film producing method involves immersing bacterial cellulose in deionized water. The bacterial cellulose is dispersed in deionized water. Graphene and surfactant are added to slurry. The bacterial cellulose slurry is added to graphene dispersion liquid to obtain mixed liquid A. Pyrrole monomer is dispersed in deionized water and added to mixed liquid A. The mixture is stirred to obtain mixed liquid B. Ammonium sulfate is dissolved in deionized water and added to mixed liquid B. The obtained mixture is subjected to in situ oxidation polymerization, filtered and dried. USE - Method for producing electrically conductive film that is utilized as cathode material in supercapacitor (claimed). ADVANTAGE - The method enables producing the electrically conductive film in a simple manner, and with better capacity rate, high quality, controllable conductivity and large-scale mass production. DETAILED DESCRIPTION - An electrically conductive film producing method involves immersing bacterial cellulose in deionized water and washing the bacterial cellulose ultrasonically. The bacterial cellulose is dispersed in deionized water uniformly and transferred to high speed stirring and homogenizing machine to obtain bacterial cellulose slurry. Graphene and surfactant are added to the slurry and dispersed in deionized water to obtain graphene dispersion liquid. The bacterial cellulose slurry is added to the graphene dispersion liquid and stirred to obtain mixed liquid A. Pyrrole monomer is dispersed in deionized water and added to the mixed liquid A, where molar ratio of the pyrrole monomer and ammonium sulfate is 0.5-15:1. The obtained mixture is stirred to obtain mixed liquid B. Ammonium sulfate is dissolved in deionized water to obtain ammonium sulfate solution. The ammonium sulfate solution is added to the mixed liquid B and subjected to in situ oxidation polymerization to obtain polypyrrole coated-graphene bacterial cellulose composite material, where molar ratio of the composite material and bacterial cellulose is 8-0.2:1. The polypyrrole coated-graphene bacterial cellulose composite material is vacuum-filtered and dried to obtain electrically conductive material, where molar ratio of the electrically conductive material and graphene is 50-2:1.
