▎ 摘  要

NOVELTY - Composite comprises a reduced oxidized graphene sheet, carbon nanotube formed on surface of the reduced oxidized graphene sheet, and manganese dioxide nanoparticles formed on surface of the reduced oxidized graphene sheet. USE - The composite is useful to produce electrode for supercapacitor (claimed). ADVANTAGE - The composite exhibits excellent cycle stability and reduction capacity. The method is simple. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) electrode comprising the composite; and (2) producing composite, comprising (a) dispersing functionalized carbon nanotube and oxidized graphene in water, and suspending the obtained product by ultrasonic treatment, (b) adding permanganate into the suspended solution, and stirring, (c) heating the stirred reaction mixture in an electronic oven, and cooling to room temperature, and (d) washing the cooled reaction mixture, and drying.
