The solid phase is washed and dried to obtain graphene load manganese dioxide, followed by preparing beta -cyclodextrin polymer-modified graphene load manganese dioxide and preparing graphene load manganese dioxide layer assembly. USE - Method for preparing supermolecule graphene load manganese dioxide assembly. ADVANTAGE - The method enables preparing the supermolecule graphene load manganese dioxide assembly with improved electrochemical performance. DETAILED DESCRIPTION - A supermolecule graphene load manganese dioxide assembly preparing method involves preparing graphene load manganese dioxide by reacting water solution , manganese sulfate, potassium permanganate and reduced graphene taking water solution and manganese sulfate, and carrying out centrifugal separation to obtain solid phase. The solid phase is washed and dried to obtain graphene load manganese dioxide, followed by preparing beta -cyclodextrin polymer-modified graphene load manganese dioxide and preparing graphene load manganese dioxide layer assembly by mixing aqueous solution of polyethylene glycol biadamantane with beta - cyclodextrin polymer-modified graphene load manganese dioxide under magnetic stirring until the end of the reaction, carrying out centrifugal separation and drying to obtain a solid phase, that was supramolecular Graphene load manganese dioxide self-assembly.
