Claim:
1. A method for repairing reduced graphene oxide, the method comprising the following steps: dispersing the reduced graphene oxide into a solvent to obtain a graphene dispersion liquid, adding a first Lewis acid and a compound containing a methyl or methylene group to obtain a first mixture, reacting the first mixture in a microwave environment of which power is 300-900 W for 0.5-2 hours, refluxing for 3-5 hours; separating, purifying and drying to obtain a first crude product; adding the first crude product into a second Lewis acid and adding an aromatic hydrocarbon repairing agent to obtain a second mixture, reacting the second mixture to obtain a molten solid, separating and purifying the molten solid to obtain a second crude product; and, mixing the second crude product, a metal powder catalyst and a third Lewis acid to obtain a third mixture, reacting the third mixture in the atmosphere of a protection gas containing a carbon source at a temperature of 450-500° C. for 1-2 hours, and annealing in a vacuum environment for 5-8 hours under a temperature of 200° C.-350° C., cooling to a room temperature, separating and purifying to obtain a repaired reduced graphene oxide.
