“…It is one of the important green chemistry processes to prepare multifunctional polymers. This method has been widely used to prepare different types of conducting polymers and their different derivatives [1,5,[9][10][11][12][13][14][15][16][17]. The preparation of nanocomposite of PPy and organic nanoparticles becomes a novel challenge for investigators.…”

Silver nanoparticles were synthesized by chemical reduction method. The surface of silver nanoparticles (SNPs) was modified using polyvinylpyrrolidone to make them more compatible with pyrrole. Surface-modified SNPs were dispersed in pyrrole and polymerized via in situ oxidative polymerization technique. The molar ratio of monomer unit to initiator and dopant was 1:1:1 and the weight percent of SNPs in polymer matrix was varied from 1 to 10. The properties of polypyrrole-silver nanocomposites have been characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscope, transmission electron microscope, thermo-gravimetric analysis and four-probe resistivity meter. All these characterizations indicate that the polypyrrole-silver nanocomposite is successfully synthesized via in situ oxidative polymerization and electrical extent shows suitable conductivity.

“…The peak at approximately 1629 cm −1 and 1550 cm −1 could be ascribed to C-N and C-C asymmetric and symmetric ring vibration.The arrangement of peaks confirms the synthesis of PPy. [43][44][45] The FTIR spectra suggest that all the characteristic peaks of PPy and FMWCNTS are present in nanocomposite (PPy-FMWCNTS) and C-H, C-C, N-H become weaker and C-N bond become stronger in nanocomposite. It is found that inclusion of FMWCNTS into PPy results a little peak shift with enhanced intensity, this is due to the presence of carboxy group on the nanotube surface that gives the interaction on the different reaction sites of PPy that facilitate the fast electron transport between PPy and FMWCNTS.…”

This paper demonstrates the facile synthesis of high performance silver-polypyrrole-multiwall carbon nanotubes (Ag-PPy-FMWCNTS) nanocomposites via electrodeposition method on stainless steel substrate and its application as a low cost counter electrode (CE) for the precious platinum (Pt) free DSSC. The nanocomposites were characterized by variety of techniques such as Fourier transforms infrared (FTIR), X-ray diffraction, Scanning electron microscope (SEM), cyclic voltammetry (CV) and Four probe technique respectively. The cyclic voltammetry and Tafel polymerization measurements of Ag-PPy-FMWCNTS nanocomposites CE reveal the favorable electrocatalytic activity and low charge transfer resistance Rct(2.50 Ω cm2) for I3−/I− redox solution. The four probe studies showed the large electrical conductivity (226S cm−1) of Ag-PPy-FMWCNTS nanocomposite. The DSSC assembled with Ag-PPy-FMWCNTS nanocomposites CE display the considerable short circuit current density (13.95 mA cm−2) and acceptable solar to electrical conversion efficiency of 7.6%, which is higher to the efficiency of DSSC with thermally decomposed Pt reference electrode 7.1%. The excellent conversion efficiency, rapid charge transfer in combination with low cost and simple fabrication method of Ag-PPy-FMWCNTS nanocomposites can be exploited as an efficient and potential candidate to replace the Pt CE for large scale production of DSSC.

“…Addition of CNT to conducting polymer, such as PEDOT, results in a significant increase in the mechanical properties and enhances electrical properties of the polymer by facilitating the charge transfer processes. Thus, in recent years, more and more attentions were inclined to the synthesis of conducting polymer/CNT composites that have special properties of the individual components in a synergistic manner [31,32].…”

Phenol and chlorophenols were investigated using single-wall carbon nanotubes (SWCNT) and poly(3,4-ethylenedioxythiophene) (PEDOT) composite modified glassy carbon electrode (SWCNT/PEDOT/GCE) as a detector in flow injection system. Optimization of experimental variables such as the detection potential, flow rate, and pH of the carrier solution (0.1 M sodium acetate) for the determination of phenol (P), 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP) were performed. Under these conditions, analytical parameters were calculated from the calibration curve of measured amperometric responses as a function of concentrations of phenol and chlorophenols. The designed electrode exhibited very good analytical performance. The designed electrode was tested with 20 repetitive injections of each analyte and showed good operational stability. The analytical performance of the SWCNT/PEDOT/GCE electrode under flow through conditions was tested and was found to be impressive. The electrode showed a wider dynamic range for the detection of phenol and chlorophenols with low limits of detection compared with other enzymatic and nonenzymatic sensors. These results suggest that the method is quite useful for the analysis and monitoring of phenols and chlorophenols.
