PPy/PAN/镀银尼龙纱线状超级电容器的制备及其性能
Preparation of PPy/PAN/silver-plated nylon yarn-like supercapacitor and its performance
摘要
Abstract
In order to equip smart wearable textile and apparel with energy storage device with high comfort and excellent performance,a kind of core-spun yarn with conductive silver plated nylon yarn as core yarn and electrostatic spinning nanofiber as cladding layer was prepared.Polypyrrole/polyacrylonitrile/silver plated nylon yarn nanofiber core-spun yarn electrode was prepared by in-situ polymerization of polypyrrole.The effect of polymerization time of pyrrole on the structure and properties of the electrode was studied.Through observation and calculation,with the increase of polymerization time of pyrrole,the polypyrrole particles on the surface of nanofibers gradually in-crease and accumulate.When employing 0.3 mol/L pyrrole concentration with 1.5 h polymerization time,the op-timized PPy/PAN/ANY yarn electrode achieves exceptional electrochemical performance,exhibiting an areal ca-pacitance of 326.58 mF/cm2 at 1 mA/cm2 current density.The assembled PPy/PAN/ANY yarn-shaped superca-pacitor demonstrates an areal capacitance of 274.7 mF/cm2,energy density of 0.038 2 mW·h/cm2,and power density of 4.976 mW/cm2 at 1 mA/cm2,while maintaining excellent flexibility.This innovative architecture ex-hibits promising potential for smart wearable textile applications due to its superior electrochemical characteris-tics and mechanical durability.关键词
