Polymer conductive composite and preparation method thereof

The invention provides a polymer conductive composite. The polymer conductive composite is composed of conductive nano-wires of one-dimensional structures, graphene of a two-dimensional structure and a spherical polymer matrix. The advantages of the one-dimensional conductive nano-wire materials and the two-dimensional graphene are combined, the two-dimensional graphene and the polymer matrix are compounded and then compounded with the one-dimensional conductive nano-wires with high length-diameter ratios and excellent electrical performance, and therefore dispersion uniformity of conductive filler in the polymer matrix is improved, and the contact chance between the conductive filler in the polymer composite is increased; through the synergistic effect of the one-dimensional conductive nano-wires and the two-dimensional graphene, an efficient conductive path network is established, and conductivity of the polymer composite is improved. The invention further provides a preparation method of the polymer conduc
