Fabric electrodes coated with polypyrrole nanorods for flexible supercapacitor application prepared via a reactive self-degraded template

Wearable energy storage devices that can be used in the garment industry are strongly required to power E-textiles. In this article, polypyrrole (PPy) nanorods were deposited on cotton fabrics via in situ polymerization of pyrrole in the presence of the fibrillar complex of FeCl3 and methyl orange as a reactive self-degraded template. The obtained fabrics could be directly used as supercapacitor electrodes, with a maximum specific capacitance of 325 F g(1) and an energy density of 24.7 Wh kg(1) at a current density of 0.6 mA cm(2). The capacitance remained higher than 200 F g(1) after 500 cycles. (C) 2015 Elsevier B. V. All rights reserved.
