Abstract
Wearable power devices were developed, using common textiles as the platform. An extremely simple dipping and drying process using single-walled carbon nanotube (SWNT) ink highly conductive textiles were obtained, with cond. of 125 S-cm-1 and sheet resistance of less than 1 W/sq. Such conductive textiles show outstanding flexibility and stretchability and demonstrate strong adhesion between the SWNTs and the textile fibers. Super-capacitors made from these conductive textiles show high areal capacitance, up to 0.48 F/cm2, and high specific energy. Loading of pseudo-capacitor materials into the conductive textiles led to a 24-fold increase of the areal capacitance of the device. These highly conductive textiles can provide new design opportunities for wearable electronics and energy storage applications.
