Description

technical field [0001] The invention relates to a preparation method of a polyaniline composite material. Background technique [0002] Polyaniline has become a research topic due to its good thermal stability, chemical stability and electrochemical reversibility, excellent electromagnetic wave absorption capacity, potential solution and melt processing performance, easy availability of raw materials, simple synthesis method and unique doping phenomenon. One of the fastest-growing conductive polymers. However, pure polyaniline is an insulator, and a single electrode material has some problems that cannot be solved by itself, such as low specific capacitance, poor cycle performance, and high price. In order to make up for the defects of single components, composite electrode materials have become the main research trend in the development of supercapacitor electrode materials. [0003] Nano-nickel powder is an important magnetic metal material, which has broad application p...
