Electrochemically synthesized stretchable polypyrrole/fabric electrodes for supercapacitor
Wearable electronics offer the combined advantages of both electronics and fabrics. Being an indispensable part of these electronics, lightweight, stretchable and wearable power sources are strongly demanded. Here we describe a daily-used cotton fabric coated with polypyrrole as electrode for stretchable supercapacitors. Polypyrrole was synthesized on the Au coated fabric via an electrochemical...
متن کاملXIX. Electrochemical Behavior at Polypyrrole-Nafion and Polypyrrole-Clay Thin Films on Glassy Carbon Electrodes
Biconductive films, involving the incorporation of an electronically conductive phase within an ionically conductive one, on glassy carbon electrode surfaces have been prepared by electropolymerization to form polypyrrole (PP) in matrices of Nation and the clay, hectorite. These films display electronic conductivity and higher stability than films of PP alone. Electrochemical studies of several...
متن کاملGraphene/polyaniline woven fabric composite films as flexible supercapacitor electrodes.
We report the design and preparation of graphene and polyaniline (PANI) woven-fabric composite films by in situ electropolymerization. The introduction of PANI greatly improves the electrochemical properties of solid-state supercapacitors which possess capacitances as high as 23 mF cm(-2), and exhibit excellent cycling stability with ∼ 100% capacitance retention after 2000 cycles. The devices h...
متن کاملChemical versus electrochemical synthesis of carbon nano-onion/polypyrrole composites for supercapacitor electrodes.
The development of high-surface-area carbon electrodes with a defined pore size distribution and the incorporation of pseudo-active materials to optimize the overall capacitance and conductivity without destroying the stability are at present important research areas. Composite electrodes of carbon nano-onions (CNOs) and polypyrrole (Ppy) were fabricated to improve the specific capacitance of a...
متن کاملSynthesis and Characterization of Polypyrrole (PPy) Thin Films
Polypyrrole (PPy) was synthesized by chemical oxidative polymerization technique using monomer pyrrole and ammonium persulphate as an oxidant in a ratio of 1:1. Thin films of polypyrrole were prepared by dissolving polypyrrole in m-cresol and cast using spin coating technique on glass substrates. Thin films of polypyrrole were characterized by X ray diffraction (XRD), Scanning electron microsco...
