•Poly(pyrrole)-coated cotton fabrics were prepared in mixed surfactants.•The fabrics are soft, lightweight, mechanically robust, and highly electrical conductive.•Potential applications of the fabrics as flexible electrodes were tested.•The fabric electrodes exhibited high discharge capacity and excellent cycling performance.
In recent years, much effort has been dedicated to achieve lightweight, stretchable and flexible energy-storage devices for wearable electronics. Here we report an everyday cotton fabric coated with poly(pyrrole) as flexible electrodes. Poly(pyrrole) nanoparticles are synthesized on the fabrics via a simple chemical polymerization process with the mixed surfactants of cetyltrimethylammonium bromide (CTAB) and sodium dodecyl benzene sulfonate (SDBS) as soft template. A highly conductive fabric with surface resistance of 14 Ω/□ can be produced by changing surfactant concentration. Such a conductive textile shows outstanding flexibility and stretchability, and demonstrates strong adhesion between the PPy and the cellulose fiber. The fabric electrode exhibits a discharge capacity of 51.7 mAh g−1 with high cycling stability (negligible decay after 100 cycles).
