Title:
FLEXIBLE CONDUCTIVE FIBER MEMBRANE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/114321
Kind Code:
A1
Abstract:
Disclosed are a flexible conductive fiber membrane material and a preparation method therefor. The method comprises: dissolving a fiber matrix material, a conductive nanomaterial and a surfactant in an organic solvent to prepare a spinning solution; preparing the spinning solution into a nanofiber membrane by means of an electrostatic spinning process; and carrying out in situ polymerization on a conductive polymer on the nanofiber membrane to prepare a flexible conductive fiber membrane material, wherein, the nanofiber membrane has a structure of primary main fibers and secondary cobweb fibers connected with each other, and the conductive polymer is formed on the primary main fiber and the secondary cobweb fiber by means of in-situ polymerization. The specific surface area of a fiber in a sample is increased due to the presence of the cobweb fiber, thus providing more bonding sites for the adhesion of the conductive polymer during an in-situ polymerization reaction, and greatly improving the conductive performance of the conductive fiber membrane material.
