▎ 摘　　要

NOVELTY - A tungsten disulfide/graphene oxide composite material comprises tungsten disulfide nanosheets and graphene oxide, where the tungsten disulfide nanosheets are interspersed between the sheets of graphene oxide and the tungsten disulfide nanosheet and the graphene oxide interpenetrate and interpenetrate. USE - Tungsten disulfide/graphene oxide composite material for use in electrode material and supercapacitor or battery (claimed). ADVANTAGE - The tungsten disulfide/graphene oxide composite material has excellent material of electrode of the device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a tungsten disulfide/graphene oxide composite material, which involves mixing homogeneous mixture of tungsten disulfide powder and sodium nitrate with concentrated sulfuric acid at a temperature of 0 degrees C and adding potassium permanganate to continue the reaction to obtain a first reaction mixture, adding deionized water and hydrogen peroxide sequentially to the first reaction mixture at room temperature to continue the reaction to form a second reaction mixture, separating the uniform dispersion of the tungsten disulfide nanosheets from the second reaction mixture and mixing tungsten disulfide nanosheet with the graphene oxide in an aqueous phase system to obtain the finished product.
