▎ 摘　　要

NOVELTY - Water is added to oxidized graphene gel and ultrasonically treated, to obtain oxidized graphene dispersion. Polyanthraquinone precursor is dissolved and ultrasonically treated, to obtain anthraquinone solution. Oxidized graphene dispersion is mixed with anthraquinone solution and ultrasonically treated, to obtain mixed solution. A catalyst is added to mixed solution. The mixture is stirred, to obtain composite solution. The composite solution is reacted under hydrothermal condition, to obtain anthraquinone-modified composite electrode material. USE - Preparation of anthraquinone-modified composite electrode material used for preparing electronic component (claimed) e.g. supercapacitor. ADVANTAGE - The method enables preparation of anthraquinone-modified composite electrode material with excellent mechanical property and electrochemical activity. The electronic component comprising anthraquinone-modified composite electrode material has excellent electrical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage of anthraquinone-modified composite electrode material for preparation of electronic component.
