NOVELTY - Preparing modified graphene oxide-piezoelectric polymer thin film energy storage device involves blending perfluorophenyl azide and graphene oxide in ethyl alcohol and then dispersing the obtained material ultrasonically. The dispersed material is heated to remove solvent and then the heated material is centrifuged to remove perfluorophenyl azide. The obtained material is freezed and dried and then the dried material is dispersed with N,N-dimethylformamide. The dispersed material is added with polyvinylidene fluoride-hexafluoropropylene copolymer and then the obtained material is heated. USE - Method for preparing modified graphene oxide-piezoelectric polymer thin film energy storage device (claimed). DETAILED DESCRIPTION - Preparing modified graphene oxide-piezoelectric polymer thin film energy storage device involves blending perfluorophenyl azide and graphene oxide in ethyl alcohol and then dispersing the obtained material ultrasonically. The dispersed material is heated to remove solvent and then the heated material is centrifuged to remove perfluorophenyl azide. The obtained material is freezed and dried and then the dried material is dispersed with N,N-dimethylformamide. The dispersed material is added with polyvinylidene fluoride-hexafluoropropylene copolymer and then the obtained material is heated and stirred to obtain composite film. The obtained composite film is heated and dried to remove solvent and then the dried material is cooled. The cooled film and substrate are immersed in water and then the film is removed for bonding upper and lower sides of the film to a copper foil. The lead wires or other electrically conductive foil material is directly connected to test equipment.
