“…Fig. 4 shows typical 'cauliflower' like structures on the electrolyte-facing surface of such films, similar to those previously observed at polypyrrole films polymerised in the presence of p-toluene sulfonic acid [41]. Notably, the film surface is not flat, but consists of a series of peaks and valleys with considerable surface roughness associated with a high degree of film porosity.…”

“…3b) electrodes illustrating the surface morphology of the free standing films. The morphology of the both films features a cauliflower-like nodule structure composed of microspherical grains, which is related to dopant intercalation in the polymeric chain [18]. The free-standing films can be rolled up (inset of Fig.…”

Electrochimica Acta, 83 209-215.All-polymer battery system based on polypyrrole (PPy)/para (toluene sulfonic acid) (pTS) and polypyrrole (PPy)/indigo carmine (IC) free standing films AbstractIn this study, we introduce a novel all-polymer battery system based on conducting polymer (polypyrrole, PPy) doped with dopants of para (toluene sulfonic acid) (pTS) and indigo carmine (IC), respectively. The performance of the systems consisting of polypyrrole-para (toluene sulfonic acid) (PPy-pTS) as cathode and polypyrrole-indigo carmine (PPy-IC) as anode in conjunction with either a polymer based electrolyte or a commercial organic electrolyte of 1M LiPF 6 in a 50:50 (v/v) mixture of ethylene carbonate (EC) and dimethyl carbonate (DMC) was evaluated. In the system, all the free-standing PPy-pTS and PPy-IC films were directly used without needing any metal substrate support to hold the electro active material. Electrochemical measurements demonstrated that the PPy-pTS/PPy-IC (commercial electrolyte) system exhibited a reversible discharge capacity of 36 mAh g -1 at 0.05 mA cm -2 after 50 cycles, is 92% of the initial discharge capacity. In the case of PPy-pTS/PPy-IC (polymer electrolyte), the reversible discharge capacity after 50 cycles was 16 mAh g -1 , 76% of the intial discharge capacity. This work deals with the fabrication of a novel all polymer battery system, with significant advantages in terms of capacity and reasonable stability. This may lead to a future generation of all polymer batteries that are suitable for implanted medical devices used in biological and biomedical systems. (c) 2012 Elsevier Ltd. All rights reserved. AbstractIn this present study, we introduce a novel all-polymer battery system based on conducting polymer (polypyrrole, PPy) doped with redox-active compounds of para (toluene sulfonic acid) (pTS) and indigo carmine (IC), respectively. The performance of the systems consisting of polypyrrole-para (toluene sulfonic acid) (PPy-pTS) as cathode and polypyrrole-indigo carmine (PPy-IC) as anode in conjunction with gel polymer electrolyte and commercial electrolyte of 1M LiPF 6 are evaluated. In the system, all the free-standing PPy-pTS and PPy-IC films were directly used without need any metal substrate to act as an electrical conductor.Electrochemical measurements demonstrated that the PPy-pTS/PPy-IC (commercial electrolyte) system exhibited a discharge capacity of 36 mAh g -1 at 0.05 mA cm -2 after 50 cycles, which is around 92 % of the initial discharge capacity. In the case of PPy-pTS/PPy-IC (polymer electrolyte), the discharge capacity retention was 16 mAh g -1 , which is also 76 % of the intial discharge capacity. The capacity degradation rate was calculated only 0.16 and 0.48 %/cycle for the PPy-pTS/PPy-IC (commercial electrolyte) and PPy-pTS/PPy-IC (polymer electrolyte) system, respectively, confirming stable cycling performance...

“…(Eslami et al, 2019) Regarding the state of the art of the theme addressed in this study, it is observed that references on "Chemical and electrochemical deposition of polypyrrol on lead alloy surface" are scarce (Eftekhari & Ahmadi, 2006). Regarding deposition on metallic substrates such as magnesium, copper, aluminum, zinc, stainless steel, there is a good database previously published (Menkuer & Ozkazank, 2019;Vera et al, 2014;Sheng et al, 2014;Mortazavi et al, 2019;Samad et al, 2019;Sharifirad et al, 2010;Annibaldi, Rooney, & Breslin, 2012;Ferreira, Liu, & Cho, 2018;Souza, Liu, & Cho, 2018;Liu, Bezerra, & Cho, 2017).…”

Polypyrrole (PPy) layers were deposited on lead metallic surface using hydrogen peroxide or benzoyl peroxide as oxidizing agent associated with different types of dopants: phosphoric acid, stearic acid and dodecylbenzene sulfonic acid. Lead alloy was chosen because of its importance in energy industrial application and also because its primary source of extraction is running out, there is an increasingly urgent need to extend its life cycle. For the in situ chemical deposition of PPy, it was considered the combination of only one oxidizing agent and one dopant, being the experiment performed with the combination of these reagents. The morphology and corrosion protection effectiveness of the PPy layer was studied by Scanning Electron Microscope (SEM), Open Circuit Potential (OCP) and Potentiodynamic Polarization. The experimental results demonstrate that PPy layer was effectively formed as a coating layer and Hydrogen Peroxide performed better and consistent protection efficiency when compared to Benzoyl Peroxide.
