Description

technical field [0001] The invention belongs to the technical field of linear fibers, and more specifically, the invention relates to an ultrahigh conductivity polymer fiber, a linear supercapacitor group and a preparation method thereof. Background technique [0002] Wearable and e-textiles are attracting great attention and occupying a dominant position in portable electronic devices. Among them, flexibility is one of the essential conditions. Among various flexible energy devices, wire-like supercapacitors are more suitable for wearable devices and electronic fabrics. Flexible fibers with high electrical conductivity can reduce energy loss and improve efficiency. Besides traditional metal wires, conductive polymer fibers are widely used in energy storage due to their high electrical conductivity, high flexibility, light weight, and fast oxygen reduction conversion rate. Convert device. Conductive polymers such as polyaniline (PANi), polypyrrole (PPy) and polyethylenedi...
