“…Considering the availability in the market of electroactive carbon materials, carbon nanotubes, fullerenes, graphenes, porphirines, ftalocianines, or oxides exchanging anions or cations during charge/discharge, a plethora of different batteries with different characteristics are being designed where at least one of the electrodes is a conducting polymer. [114][115][116][117] The availability of thin films of ionic conducting polymeric membranes allows the construction of both, hybrid batteries (ELECTRODE/membrane/CP), where the material of the electrode is non-polymeric (metal, alloy, oxide, intercalation compound, etc.) or all polymeric batteries (CP/membrane/CP).…”

Electro-generations of conducting polymers are fast processes through a complex mechanism of parallel reactions giving mixed materials. The films are three-dimensional electrochemical reactors: reactive macromolecules, ions, and solvent. The film composition and its related properties reviewed here change by oxidation/reduction along several orders of magnitude under control. One reaction shifts different properties (multifunctionality). In one device several reaction driven tools, actuators and sensor, work simultaneously (full integration

“…However, to the best of the authors' knowledge, the application of ICPs coated fabric in stretchable supercapacitors has not been reported, though recently we have reported the stretchable buckle-structured polypyrrole integrated into a SIBS substrate for Mg batteries [9]. In particular, ICPs are interesting candidates for flexible energy storage devices due to their relatively high theoretical capacities, fast redox properties, lightweight and mechanical flexibility [10][11][12][13][14]. A flexible ultrafast all-polymer battery composed of PPy coated cellulose fibres electrodes could be charged with currents as high as 600 mA cm -2 with only 6% capacity loss over 100 subsequent charge and discharge cycles [15].…”

, GG (2012), Polypyrrole coated nylon lycra fabric as stretchable electrode for supercapacitor applications, Electrochimica Acta, 68, Polypyrrole coated nylon lycra fabric as stretchable electrode for supercapacitor applications AbstractWearable 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 nylon lycra fabric coated with polypyrrole as electrode for stretchable supercapacitors. Polypyrrole was synthesized on the fabric via a simple chemical polymerization process with ammonium persulfate (APS) as an oxidant and naphthalene-2,6-disulfonic acid disodium salt (Na 2 NDS) as a dopant. This material was characterized with FESEM, FTIR, tensile stress, and studied as a supercapacitor electrode in 1.0 M NaCl. This conductive textile could endure 1000 stretching cycles with 100% strain applied, and still retained its electrical conductivity and electrochemical properties. Interestingly, we also found that this material showed improved electrochemical properties when it was being stretched. ABSTRACTWearable electronics offer the combined advantages of both electronics and fabrics.

Water transport in poly(pyrrole/copper phthalocyaninetetrasulfonate) (PPy/CuPTS) films, where cation transport prevails, has been investigated by employing the electrochemical quartz crystal microbalance (EQCM) technique, the electrochemical impedance technique, and the electrogravimetric impedance technique. The approximate numbers of accompanying waters per cation for PPy/CuPTS films have been obtained from both cyclic EQCM experiment and impedance experiment. It is shown that the number of accompanying waters depends on the nature and concentration of an electrolyte solution as well as the redox state of the film. It increases with the hydration number of cation in an aqueous electrolyte solution and exhibits hysteresis behavior during redox cycle. It is found that ionic conductivity of cation in a film depends on the number of accompanying waters and the ion-ion interactions inside the film. It is also found that a substantial amount of water moves with the cation during the break-in process at the first cathodic scan. Moreover, the electromechanical impedance technique has been employed to verify the relation between mass and resonant frequency of an oscillating quartz crystal and to monitor morphology changes (viscoelastic change and volume change) during the redox reaction of PPy/CuPTS films. It is found that mass change can be obtained from resonant frequency without consideration of morphology changes of PPy films. It is also found that morphology changes of PPy/CuPTS films relate to the amount of water moving into or out of the film.
