Abstract

The invention belongs to the technical field of composite conductive materials and particularly relates to an ethylene-vinyl acetate copolymer / polyaniline composite conductive material and a preparation method thereof. The preparation method comprises the steps of firstly preparing an ethylene-vinyl acetate copolymer porous membrane, and then carrying out in situ polymerization on the ethylene-vinyl acetate copolymer porous membrane and aniline so as to prepare the ethylene-vinyl acetate copolymer / polyaniline composite conductive material. According to the preparation method, the problem that conductive polyaniline is absorbed by an EVA matrix is thoroughly solved. The preparation method has the advantages that the preparation process condition is easily realized, the cost is saved, and the conductivity of the ethylene-vinyl acetate copolymer / polyaniline composite conductive material is excellent.

Description

[0001] technical field [0002] The invention belongs to the technical field of composite conductive materials, and in particular relates to an ethylene-vinyl acetate copolymer / polyaniline composite conductive material and a preparation method thereof. Background technique [0003] Since American scientists A.J.Heeger and A.G.MacDiarmid and Japanese scientist H.Shirakawa discovered that doped polyacetylene (PA) has metal conductive properties in 1977, the concept that organic polymers cannot be used as conductive materials has been completely changed, and a new technology was born. A new interdisciplinary subject-conductive polymer. After the discovery of conductive polyacetylene, a series of conjugated polymers such as polyparaphenylene, polypyrrole, and polyaniline have been doped to have high conductivity. The study of conductive polymer materials not only has theoretical academic value, but also has high application value. [0004] Compared with other conductive polyme...
