Abstract

The invention discloses a polypyrrole supercapacitor composite electrode material on the basis of electrostatic spinning nano-fiber yarn forming technologies and a method for preparing the polypyrrolesupercapacitor composite electrode material. Electrodes are of core-spun yarn structures, skin layers are nano-fibers, polypyrrole which is a conductive polymer is attached to the surfaces of the nano-fibers, and core layers are conductive cotton yarns. The method includes carrying out alkali boiling, acid leaching and sensitization and activation on cotton yarns, and then treating the cotton yarns in chemical nickel plating mixed liquid at the temperature of 30-70 DEG C for 2-6 h to obtain the conductive cotton yarns; preparing core-spun yarns by the aid of the electrostatic spinning nano-fiber yarn forming technologies; polymerizing pyrrole monomers at the temperatures ranging from -2 DEG C to 10 DEG C to obtain supercapacitor polypyrrole electrodes. A molar ratio of the pyrrole monomers to anhydrous ferric trichloride is 1:1-3.
