NOVELTY - A graphene self-assembly preparing method involves preparing beta-ring dextrin refined embellish poly oxidation graphene. Beta ring dextrin refined poly embellish reduction graphene is prepared followed by preparing graphene layer from reduction assembly by taking beta-ring dextrin refined poly embellish reduction graphene dispersing in deionized water and adding polyethylene glycol, stirring reaction after through centrifugal treatment, centrifuging to obtain solid phase after washing and vacuum drying to obtain the graphene layer from reduction. USE - Method for preparing graphene self-assembly for super-capacitors. ADVANTAGE - The self-assembly greatly increases the specific capacitance, thus indicating that the graphene self-assembly body and is good in application prospect. DETAILED DESCRIPTION - A graphene self-assembly preparing method involves preparing beta-ring dextrin refined embellish poly oxidation graphene by taking oxidation graphene, dispersing in deionized water and again adding beta-poly ring paste refined solution by centrifugal separation after ultrasonic treatment, taking solid phase drying to obtain the beta-ring dextrin refined embellish poly oxidation alkene. Beta ring dextrin refined poly embellish reduction graphene is prepared by taking beta-ring dextrin refined embellish poly oxidation graphene aqueous solution and potassium hydroxide, hydration hydrazine,mixing for reaction, to obtain beta ring dextrin refined poly embellish reduction graphene, followed by preparing graphene layer from reduction assembly by taking beta-ring dextrin refined poly embellish reduction graphene dispersing in deionized water and adding polyethylene glycol, stirring reaction after through centrifugal treatment, centrifuging to obtain solid phase after washing and vacuum drying to obtain the graphene layer from reduction.
