A hybrid doped polypyrrole paper-based flexible electrode material and its preparation method

Abstract

The invention discloses a hybrid doped polypyrrole paper-based flexible electrode material. The preparation steps include dissolving a certain amount of lignosulfonate and sodium anthraquinone-2-sulfonate in a certain amount of distilled water at the same time, Obtain a hybrid doping solution; disperse a certain amount of cellulose fiber in the hybrid doping solution, and place it in an ice-water bath. After mechanical dispersion, add a certain amount of pyrrole monomer, and after mechanical stirring for a certain period of time, add it dropwise The ferric chloride oxidizing agent solution initiates polymerization; after polymerization for a certain period of time, the product is filtered, washed and dried to obtain a hybrid doped polypyrrole paper-based flexible electrode material. The invention has the advantages of simple process, readily available raw materials, and is suitable for large-scale industrial production, and the prepared hybrid doped polypyrrole paper-based flexible electrode material has the characteristics of low cost and high specific capacity.
