Abstract

The invention discloses a preparation method of a composite material, the composite material and a super-capacitor, and belongs to the technical field of nano materials. The preparation method of thecomposite material comprises the following steps: preparing a titanium dioxide nanorod array; dissolving aniline in first hydrochloric acid solution to form first solution, dissolving ammonium persulfate in second hydrochloric acid solution to form second solution, mixing the first solution with the second solution, and performing violent shaking for 20-40s to obtain mixed solution; putting the titanium dioxide nanorod array into the mixed solution for reacting for 1-3 hours to obtain a titanium dioxide nanorod array; performing washing to obtain the titanium dioxide and polyaniline nano composite material. The preparation method of the composite material is simple in preparation process, low in manufacturing cost and good in repeatability.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a preparation method of a composite material, a composite material and a supercapacitor. Background technique [0002] Supercapacitor is an innovative product compared with traditional batteries and capacitors. Its fast charge and discharge rate, high energy density, power density, and its environmental friendliness and relatively long cycle life make it more and more popular. The attention of scientific research workers has broad application and development prospects. [0003] However, supercapacitors in the prior art are generally prepared from carbon nanotubes, metal oxides, etc. However, the supercapacitors prepared by this method have problems such as high raw material costs, difficult availability of raw materials, and complicated preparation processes. Contents of the invention [0004] The invention provides a method for preparing a composite material, a co...
