Problems solved by technology

[0003] However, the stability and mechanical properties of conductive polypyrrole materials are poor. In order to improve and enhance the performance of polypyrrole, a large number of researchers have focused on the composite of polypyrrole and other materials. In recent years, the composite of carbon materials such as carbon nanotubes has been widely used. Expanded, the research results show that the composite with carbon nanotubes can greatly improve the performance of supercapacitors, but carbon nanotubes have disadvantages such as high cost and low specific capacitance, so the purpose of this invention is to study a new inorganic filler composite polypyrrole materials, in order to improve the stability, strength and mechanical properties of polypyrrole
