Preparation method of polyaniline/graphene/nano nickel composite material

The invention provides a preparation method of a polyaniline/graphene/nano nickel composite material, and relates to the preparation method of the polyaniline composite material, in order to solve the problem that the polyaniline has no electrochemical performance. The preparation method comprises the following steps: 1, preparing a graphene oxide solution; 2, preparing composite powder in a graphene carrying nano nickel manner; and 3, preparing the polyaniline/graphene/nano nickel composite material. The method provided by the invention is simple, convenient and easy to implement, low in cost and high in yield, thereby being suitable for mass production. The method is applied to the field of chemical industry.
