Dual-conductive fiber network structure material and preparation method and application thereof

Abstract

Provided are a dual-conductive fiber network structure material and a preparation method and application thereof. The dual-conductive fiber network structure material, with a core of dual-phase spun fibers obtained from polyacrylonitrile fibers comprised of polyacrylonitrile and deprotonated polyaniline and chitosan gel fibers comprised of chitosan and polyvinyl alcohol (PVA), is cladded with a long-chain polyaniline shell, and can be stored for a long time. The dual-conductive fiber network structure material solves the problems of large signal-to-noise ratio and poor compliance and stability of electrodes of skin-contact devices in the prior art, and the preparation method solves the problem of difficulty in spinning the chitosan solution and the polyacrylonitrile-polyaniline solution in the prior art and reconciles the problems of stability of chitosan gel fibers and conductivity requirements of protonic acid-doped polyaniline.
