bstract：Inorder toequipsmart wearabletextileandapparel with energy storagedevice with high comfortand excellnt performance，a kind of core-spun yarn with conductive silver plated nylon yarn as core yarn and electrostatic spining nanofiber as cladding layer was prepared.Polypyrole/polyacrylonitrile/silver plated nylonyan nanofiber core-spun yarn electrode was prepared by in-situ polymerization of polypyrrle.The efect of polymerizationtime of pyroleon the structure and properties of the electrode was studied.Through observation and calculation，with the increase of polymerization time of pyrrole，the polypyrrle particles on the surface of nanofibers gradually increase and accumulate.When employing 0.3 mol/L pyrrole concentration with1.5 h polymerization time，the optimizedPPy/PAN/ANY yarn electrode achieves exceptional electrochemical performance，exhibitinganareal capacitance of 326.58 mF/cm² at1 mA/cm current density. The assembled PPy/PAN/ANY yarn-shaped supercapacitor demonstrates an areal capacitance of 274.7mF/cm2 ，energy density of 0.0382mW⋅h/cm2 ，and power densityof4.976mW/cm² at 1mA/cm2 ，while maintaining excellent flexibility. This innovative architecture exhibits promising potential for smart wearable textile applications due to its superior electrochemical characteristics and mechanical durability.
