The preparation method comprises the first step that copper nickel solid solution powder is prepared, the second step that the solid solution microemulsion is prepared through the prepared copper nickel solid solution powder, methylbenzene and SDBS, the third step that the aqueous solution of the aniline hydrochloride and the solid solution microemulsion are blended, the APS solutions are dropwise added, after stirring and reactions, the acetone is added to be stirred, then standing, suction filtration, washing and vacuum drying are carried out, and then the core-shell nano-copper nickel solid solution / polyaniline composite materials are obtained. The core-shell nano-copper nickel solid solution / polyaniline composite materials and the preparation method of the core-shell nano-copper nickel solid solution / polyaniline composite materials are applied to the field of preparing conducting materials, capacitors and electrochromic materials.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof. Background technique [0002] Among various conductive polymer materials, polyaniline is due to its cheap and easy-to-obtain monomer raw materials, simple synthesis process, special proton doping, good redox and environmental stability, high doping conductivity and other The advantages of reversible electrochemical activity make it the most promising class of polymer materials, but the difficulty of post-processing limits its practical application. At present, the methods for synthesizing polyaniline materials mainly include: chemical oxidative polymerization, emulsion polymerization, and electrochemical polymerization. Not only is the process complicated, the cost is high, and the preparation time is long, but also the yield of polyaniline is low, and the nano-metal particles are easily oxidized during the reaction. For conductive materials, capacitors and electrochromic...
