This paper presents a novel approach to fabricating highly conductive, stretchable, and porous textiles using single-walled carbon nanotube (SWNT) ink. The simple "dipping and drying" process results in textiles with a conductivity of 1.25 S cm−1 and a sheet resistance less than 1 Ω/sq. These conductive textiles exhibit excellent flexibility, stretchability, and strong adhesion between the SWNTs and the textile fibers. Supercapacitors made from these textiles show high areal capacitance (up to 0.48 F/cm2) and specific energy. The study also demonstrates the loading of pseudocapacitor materials (e.g., MnO2) into the conductive textiles, leading to a 24-fold increase in areal capacitance. This work opens new design opportunities for wearable electronics and energy storage applications, leveraging the existing textile fabrication infrastructure to achieve large-scale, low-cost energy storage solutions.This paper presents a novel approach to fabricating highly conductive, stretchable, and porous textiles using single-walled carbon nanotube (SWNT) ink.
