NOVELTY - A reduced graphene oxide conductive film is prepared by taking graphite oxide, adding deionized water, carrying out ultrasonic treatment, centrifuging, taking supernatant, drying, grinding to obtain graphene oxide, adding solvent, ultrasonic processing, vacuum filtering, taking filter cake, drying, peeling off, clamping in smooth surface and high temperature alloy mold, placing in tubular furnace, hydraulic pressing, pumping nitrogen, argon and helium gas, heating, increasing pressure, and cooling. USE - Method for preparing reduced graphene oxide conductive film (claimed). DETAILED DESCRIPTION - A reduced graphene oxide conductive film is prepared by taking graphite oxide, adding deionized water at 1 g:500-1000 mL molar ratio, carrying out ultrasonic treatment for 10 minutes to 1 hour, centrifuging at rate of 2000-3000 revolutions/minute for 5-20 minutes, taking supernatant, drying, grinding to obtain graphene oxide, adding solvent comprising deionized water, ethanol, or deionized water and ethanol mixed solution, ultrasonic processing for 0.5-1.5 hours to obtain 1-5 mg/mL graphene oxide dispersion, vacuum filtering via micropore filter film, taking filter cake, drying at 60-100 degrees C, peeling off, clamping in smooth surface and high temperature alloy mold, placing in tubular furnace, hydraulic pressing under 0-10 MPa, pumping nitrogen, argon and helium gas, heating at rate of 1-5 degrees C/minute to 600-1000 degrees C, increasing pressure to 20-40 MPa for 2-8 hours, and cooling.
