Method for preparing graphene oxide by chemical electrolysis method

The invention belongs to the field of preparation of functional materials and in particular relates to a method for preparing graphene oxide by a chemical electrolysis method. The method comprises the following steps: after adding liquid-state resin into a corresponding curing agent, coating two sides of graphite paper with a mixture in sequence and curing to form coatings; then raising the temperature and carbonizing according to a certain procedure to prepare a conducting sheet; then electrolyzing the conducting sheet to prepare a graphene oxide solution, filtering and purifying to obtain the high-purity graphene oxide. By adopting the method provided by the invention, the problem that the oxidization degree of graphene prepared by an electrolysis method is low is solved; the graphite paper is covered with a conducting carbonization layer and the graphite paper and the conducting carbonization layer are electrolyzed and oxidized, so that the prepared graphene is the graphene oxide with a high oxidization de
