Abstract

The invention relates to a capacitor, in particular to a fibrous supercapacitor and a preparation method thereof. According to the invention, a non-conductive fabric and a non-conductive fabric fiber are adopted as base materials; conductive macromolecule are subjected to polymerization and deposition to obtain a skin electrode and a core electrode of the fibrous supercapacitor; the adopted fabric and fabric fiber are soft and good in flexibility; the adopted conductive macromolecule are of a conjugated chain oxidation and corresponding anion doping structure; the obtained skin electrode and core electrode are good in electrical conductivity; the assembled fibrous supercapacitor is not only light in mass, but also simple in structure and excellent in flexibility; excellent mechanical property can be kept; the charging speed is rapid; the cycling stability is good; the specific capacity is high; the biocompatibility is good, the safety is high, no pollution is caused; and the invention is a novel fibrous supercapacitor which can be applied to the fields of embedded health monitoring and nursing.

Description

technical field [0001] The invention relates to a capacitor, in particular to a fibrous supercapacitor and a preparation method thereof. technical background [0002] Wearable electronics is a new type of electronic product developed by combining textile technology and electronic technology. It has broad application prospects in nursing and other fields. Among them, fiber supercapacitors have attracted great interest in recent years due to their excellent performance and structural characteristics. [0003] The research group of Professor Wang Zhonglin from the Georgia Institute of Technology in the United States grew zinc oxide nanowires on the surface of flexible polymethyl methacrylate (PMMA) fibers and Kevlar fibers, and then sputtered a gold conductive layer and deposited MnO on the surface. 2 Form a fiber electrode, use this fiber electrode as the two electrodes of the supercapacitor respectively, use 1M KNO 3 and PVA / H 3 PO 4 Each layer of electrolyte is made to...
