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 the compatibility between polypyrrole and carbon nanotubes is poor, and the conductive stability of the composite material is low

Description

technical field [0001] The invention belongs to the field of conductive materials, and in particular relates to a preparation method of polypyrrole conductive materials. Background technique [0002] Polypyrrole is a common black, insoluble, infusible, and conductive polymer. Polypyrrole is usually obtained by oxidative polymerization of pyrrole monomers. Electrochemical anodic oxidation of pyrrole is also an effective means of preparing polypyrrole; polypyrrole can be used in biology, ion detection, ultra- Capacitor and antistatic materials, modified electrodes for photoelectrochemical cells, and electrode materials for storage batteries. In addition, it can also be used as electromagnetic shielding material and gas separation membrane material, used in electrolytic capacitors, electrocatalysis, conductive polymer composite materials, etc. It has a wide range of applications and has attracted people's attention since it was discovered. [0003] However, the stability and m...
