▎ 摘　　要

NOVELTY - Preparing graphene-disulfide polyaniline composite electrode material comprises e.g. preparing the substrate powder and dispersing graphene in de-ionized water, where the ratio of molybdenum trioxide and potassium thiocyanate, and magnetically stirring, adding into stainless steel reaction kettle with polytetrafluoroethylene inner liner, reacting, finishing reaction, naturally cooling, centrifugal separating to obtain black precipitate product. USE - The method is useful for Preparing graphene-disulfide polyaniline composite electrode material (claimed). ADVANTAGE - The method is simple, suitable for industrial production. The material has uniform appearance, with good electrochemical performance of the electrode material and can obtain high pseudo-capacitance, an electric double layer capacitor and has a more excellent cycle performance. DETAILED DESCRIPTION - Preparing graphene-disulfide polyaniline composite electrode material comprises (i) preparing the substrate powder and dispersing graphene in de-ionized water, where the ratio of molybdenum trioxide and potassium thiocyanate is 0.4318: 0.728, and magnetically stirring, adding into stainless steel reaction kettle with polytetrafluoroethylene inner liner, reacting for 24 hours at 210 degrees C, finishing reaction, naturally cooling, centrifugal separating to obtain black precipitate product, precipitating the product by ethanol and de-ionized water, drying at 60 degrees C to obtain the substrate powder, (ii) carrying out in situ polymerization at room temperature taking proper base powder in a dilute acid in ultrasonic dispersion, adding aniline monomer and oxidant, stirring uniformly, allowing to stand at normal temperature, in-situ polymerization polyaniline on the substrate material, filtering, washing the solid in the reaction system, drying at 60 degrees C to obtain the product.
