“…Better charge retention properties were subsequently obtained153 using dry cells comprising paper composite electrodes containing PPy or PANI. Thin film batteries obtained by sandwiching a Nafion layer between thin layers of PANI coated Nafion membranes,154 thin films of PPy and PANI,155 or two thin PANI layers19 were also demonstrated. High self‐discharge rates, most likely due to reactions of the polymers with the electrolyte, were found to be a significant problem with the latter types of batteries.…”

All-polymer and paper-based energy storage devices have significant inherent advantages in comparison with many currently employed batteries and supercapacitors regarding environmental friendliness, flexibility, cost and versatility. The research within this field is currently undergoing an exciting development as new polymers, composites and paper-based devices are being developed. In this report, we review recent progress concerning the development of flexible energy storage devices based on electronically conducting polymers and cellulose containing composites with particular emphasis on paper-based batteries and supercapacitors. We discuss recent progress in the development of the most commonly used electronically conducting polymers used in flexible device prototypes, the advantages and disadvantages of this type of energy storage devices, as well as the two main approaches used in the manufacturing of paper-based charge storage devices.

“…The latter polyaniline was extensively investigated by several researchers. The electrochemical oxidation of aniline has typically been carried out in aqueous electrolytes galvanostatically,4–10 potentiostatically,11–14 or through the cycling of the potential (potentiodynamic) of the substrate anode (e.g., between −0.2 or 0.0 V and +0.8 V versus saturated calomel electrode (SCE) in 1 M HCl,11, 15 0.1 M H 2 SO 4 ,16 or 1 M H 2 SO 4 ) 10. Several electrolytes have been successfully used for the synthesis of polyaniline (e.g., HClO 4 ,4, 5, 8, 14 HCl,11, 15 H 2 SO 4 ,10, 12, 13, 17, 18 CF 3 COOH,18 and HBF 4 ) 6–8.…”

Polyaniline was electrochemically synthesized from an aqueous medium with various acid electrolytes via potentiodynamic and potentiostatic techniques. The electrochemical synthesis of polyaniline was studied over various substrates, including Pt, Ti, Ni, and SnO 2 coated glass, and in various acid electrolytes. Cyclic voltammograms of electrochemically synthesized polyaniline were studied in HCl in a pH range of 1-4. Probable electrochemistry and chemical changes were deduced that occurred when polyaniline film was electrochemically oxidized and reduced between Ϫ0.2 and 1.0 V versus a Ag/AgCl reference electrode in an acidic electrolyte at pH 1, and three corresponding oxidation and reduction peaks were described instead of two redox peaks (as observed by W. S. Huang, B. D. Humphrey, and A. G. MacDiarmid, J Chem Soc Faraday Trans 1 1986, 82, 2385). The electrochromic property was studied with changes in the chemical states of polyaniline during electrochemical oxidation and reduction. A new viscous electrolyte, aqueous AlCl 3 (pH 2), saturated with AgCl was used for the construction of an electrochromic display device.

Polyaniline (Pani) films containing CdTe, CdSe, and both nanoparticles were deposited using spin coating technique. Pani was chemically synthesized by oxidation method, whereas surfactant free CdTe and CdSe nanoparticles were prepared using solvothermal method. Binanoparticle films showed an increase in the absorption from 350 nm to the near IR region. Absorption spectra also showed charge transfer complex formation for the binanoparticle hybrid thin films prepared with weight ratio of [Pani (camphor sulfonic acid, CSA):CdTe:CdSe] 200:100:75. Photoluminescence measurement for the bi-nanoparticle hybrid thin films confirmed that the required dissociation of excitons was taking place at the interface. Scanning electron microscopy images showed homogeneity and an interconnected network on the surface of the films prepared with Pani (CSA):CdTe:CdSe weight ratios of 200:100:50 and 200:100:75, respectively. Cyclic voltammetry confirmed better stability for the bi-nanoparticle hybrid films in comparison to Pani film. It also established the process of electrochemical charge transfer between the nanoparticles and the polymer matrix.
