The preparation method of the partially reduced graphene oxide comprises evenly dispersing the graphene powder with grain diameter of 30 meshes to a sulfuric acid solution, gradually adding the potassium permanganate in the sulfuric acid solution evenly dispersed with graphene powder to form a mixed solution; adding water in the mixed solution, heating the mixed solution to raise up the temperature to 90-100 degrees C so that the graphene in the mixed solution, the potassium permanganate powder and the sulfuric acid powder are reacted to form the graphene oxide; thinning, filtering and washing the graphene oxide; dissolving he graphene oxide in the solution with pH value within 5.5-10, performing ultrasound treatment to dissolve the treatment to dissolve the graphene oxide powder and the solution with pH value of 5.5-10 to obtain the graphene oxide gel; separating out the graphene oxide from the graphene oxide gel, drying the separated graphene oxide to obtain the graphene oxide powder, using a certain quantity of reducing agent, reducing the graphene oxide powder; drying the partially reduced graphene oxide powder; obtaining the partially reduced graphene oxide. The functional treatment of the partially reduced graphene oxide comprises under the protection and drying of inert gases, mixing VR reagent in the partially reduced graphene oxide to perform the Wells Meyer-Hack A ester reaction; keeping the graphene oxide solution mixed with the VR reagent at 5-90 degrees C and reacting the graphene oxide and the acyl chloride reagent; and then removing the residual acyl chloride reagent. The polyaniline is in a shape of nano fiber, having a diameter of 30-200 nanometers and the length of 200-2000 nanometers. The preparation method of prefabricated solution of the graphene/polyaniline nanometer fiber composite material comprises under the protection and drying of inert gases, adding the conductive polymer solution in the functional treated grapheme oxide solution; continuously stirring for 15 minutes to 8 hours; obtaining the prefabricated solution of the graphene/polyaniline nanometer fiber composite material. The mass ratio of the polyaniline nanometer fiber and the grapheme oxide is 10: 1-1:5. The graphene/polyaniline nanometer fiber composite material is obtained by reacting the acyl chloride radical group on the grapheme oxide and amino on the conductive polymer. The reducing agent for partially reducing the graphene oxide is one or two of callus, 50-80% of hydrated corpus, dimethyl corpus and asymmetrical dimethyl corpus, or one or two of sodium borohydride, phenol and ethylene glycol. The weight ratio of the reducing agent for partially reducing the graphene oxide and the graphene oxide powder is 2000:1-200:10. The VR reagent is thionyl chloride, phosphorus oxychloride, phosphorus pentachloride and/or N,N-dimethylformamide. The mass ratio of the VR reagent and the graphene oxide is 2:1-300:1. The mass ratio of N,N-dimethylformamide and chlorination reagent is 1:100-1:300. An INDEPENDENT CLAIM is included for the super capacitor.
