NOVELTY - Preparing polyaniline/nickel disulfide/graphene nanofiber composite material involves using aniline as the monomer, preparing graphene nanofibers by using hydrothermal method supported nickel disulfide as the supporting framework and using ammonium persulfate as the oxidant. The composite material is made by chemical oxidation reaction under the action of ultrasound. USE - Method for preparing polyaniline/nickel disulfide/graphene nanofiber composite material. ADVANTAGE - The method enables to prepare polyaniline/nickel disulfide/graphene nanofiber composite material has high specific capacitance and excellent electrochemical cycle stability, and is mainly used to make electrodes of supercapacitors, and has significant economic value and social benefits.
