NOVELTY - Preparing graphene conductive agent comprises e.g. (i) adding concentrated sulfuric acid, flake graphite and potassium permanganate into reaction vessel, placing in constant temperature water bath box, (ii) increasing water temperature in thermostatic water bath, adding deionized water into reaction vessel to obtain brown mixture, (iii) removing reaction vessel from constant temperature water bath box and adding hydrogen peroxide solution, stirring, washing, drying and grinding to obtain graphene oxide, and (iv) placing graphene oxide in microwave oven for thermal reduction reaction. USE - The method is useful for preparing graphene conductive agent (claimed). DETAILED DESCRIPTION - Preparing graphene conductive agent comprises (i) adding concentrated sulfuric acid, flake graphite and potassium permanganate into reaction vessel, placing in constant temperature water bath box and controlling water temperature in thermostatic water bath box to react for period of time to obtain green mixture, (ii) increasing water temperature in thermostatic water bath for period of time, continue increasing water temperature in thermostatic water bath and adding deionized water into reaction vessel to obtain brown mixture, (iii) removing reaction vessel from constant temperature water bath box and adding hydrogen peroxide solution, stirring to obtain golden yellow mixture, centrifugating, washing, drying and grinding to obtain graphene oxide, and (iv) placing graphene oxide in microwave oven for thermal reduction reaction.
