Abstract

The invention discloses gel conductive fibers. The gel conductive fibers comprise, by weight, 17-20 parts of superfine silicon dioxide aerogel, 0.8-1 part of polysorbate 80, 3-5 parts of dicumyl peroxide, 40-50 parts of aniline, 1-1.5 parts of ammonium persulfate, 100-130 parts of acrylonitrile, 0.7-1 part of benzotriazole, 2-3 parts of gamma-aminopropyl triethoxy silane and 4-5 parts of oleic acid. Dispersion compatibility of the raw materials is achieved by the blending reaction of amino polymer and acid doped polyaniline. The gel conductive fibers are good in mechanical and conductive stability and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of fibers, and in particular relates to a gel conductive fiber and a preparation method thereof. Background technique [0002] Polymer materials are usually considered as insulators, but the successful development of polyacetylene conductive materials in the 1970s broke this traditional concept. After that, polymer conductive substances such as polyaniline, polypyrrole, and polythiophene were born one after another, and people's research on the conductive properties of polymer materials has become more and more extensive; conductive fiber is a new fiber variety that appeared in the 1960s. , which generally refers to fibers with conductivity greater than 10-7Ω-1.cm-1. This type of fiber has good electrical conductivity and durability, especially in low humidity and still has good durable antistatic properties, so it has great uses in industrial, civil and other fields; [0003] However, most of the current conductive...
