Abstract

The invention discloses a hybrid doped polypyrrole paper-based flexible electrode material, which is prepared by the following steps: simultaneously dissolving a certain amount of lignosulfonate and anthraquinone-2-sodium sulfonate in a certain amount of distilled water to obtain a hybrid doped solution; dispersing a certain amount of cellulose fibers in a hybrid doping solution, placing in an ice-water bath, mechanically dispersing, adding a certain amount of pyrrole monomer, mechanically stirring for a certain time, and dropwise adding a ferric trichloride oxidant solution to initiate polymerization; and after polymerizing for a certain time, filtering, washing and drying a product to obtain the hybrid doped polypyrrole paper-based flexible electrode material. The method has the advantages that the process is simple, the raw materials are easy to obtain, and the method 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.

Description

technical field [0001] The invention relates to the field of flexible electrode materials, in particular to a hybrid doped polypyrrole paper-based flexible electrode material and a preparation method. Background technique [0002] The development of flexible electronics has brought various novel applications, such as foldable mobile phones, electronic skin, implantable electronic medical equipment, etc., which continuously meet social needs and improve people's quality of life. Ideal flexible electronics can be used when bent, folded, and compressed. The development of flexible electronic devices has also created the demand for flexible energy storage systems. Therefore, the energy storage system used in flexible electronic products must be able to meet the bending and folding conditions mentioned above while meeting the requirements of energy density and power density. However, fabricating low-cost, lightweight, and environmentally friendly flexible energy storage devices...
