▎ 摘  要

NOVELTY - Preparing functionalized graphene quantum dot modified gel binder involves dissolving citric acid and functional modifier in a certain amount of water in a certain mass ratio, transferring to a reaction kettle for pyrolysis, after pyrolysis is completed and cooling to room temperature, dispersing pyrolysis product in deionized water for dialysis to obtain functionalized graphene quantum dots. The functionalized graphene quantum dots and the ion conductive polymer monomer are uniformly mixed in a certain mass ratio under the protection of nitrogen. The mixed solution system is accompanied Stir and heat to 60-100 degrees C. The initiator is added, stopped heating when the mixed solution becomes viscous, cooled to room temperature, washed with deionized water multiple times to remove excess impurities, and filtering, and dried in a vacuum drying oven not exceeding 90 degrees C to obtain a functionalized graphene quantum dot modified ion conductive gel binder. USE - Method for preparing functionalized graphene quantum dot modified gel binder used in supercapacitor electrode material (claimed). ADVANTAGE - The method enables to prepare functionalized graphene quantum dot modified gel binder that ensures the stability of the structure of the electrode, and ensures the stability of the structure of the electrode. DETAILED DESCRIPTION - Preparing functionalized graphene quantum dot modified gel binder involves dissolving citric acid and functional modifier in a certain amount of water in a certain mass ratio, transferring to a reaction kettle for pyrolysis, after pyrolysis is completed and cooling to room temperature, dispersing pyrolysis product in deionized water for dialysis to obtain functionalized graphene quantum dots. The functionalized graphene quantum dots and the ion conductive polymer monomer are uniformly mixed in a certain mass ratio under the protection of nitrogen. The mixed solution system is accompanied Stir and heat to 60-100 degrees C. The initiator is added, stopped heating when the mixed solution becomes viscous, cooled to room temperature, washed with deionized water multiple times to remove excess impurities, and filtering, and dried in a vacuum drying oven not exceeding 90 degrees C to obtain a functionalized graphene quantum dot modified ion conductive gel binder. The graphene quantum dot functionalized modified ion conductive gel binder is immersed in a certain mass ratio into electronically conductive polymerization in monomer solution, stirred in an ice water bath for 30 to 60 minutes. The initiator is slowly added to the solution, and continues to accompany the ice water bath and stirring. The reaction solution is precipitated, the precipitated product is repeatedly washed with deionized and anhydrous ethanol. The vacuum drying treatment is performed at not more than 50 degrees C to obtain a functionalized graphene quantum dot modified ion/electron double conductive gel binder.
