“…In this study, we report a simple procedure for the fabrication of PPy by in situ chemical oxidative polymerization in the presence of various amounts of the anionic electrolyte poly(styrene sulfonate) (PSS) and a milder oxidant, ammonium peroxodisulfate (APS). Although the electrochemical synthesis of PPy with PSS counterions22–24 and the chemical synthesis of PPy in the presence of PSS and Fe(III) oxidant25–27 have been reported previously, the conductivity of the fabricated PPy was smaller than 10 S cm −1 . Qi and Pickup27 reported a synthesis of PPy by in situ polymerization of pyrrole in the presence of PSS using various concentrations of Fe(III) oxidant.…”

BACKGROUND: The solubility and conductivity of chemically synthesized polypyrrole (PPy) are dependent on the synthesis procedure and composition. Enhanced processability of PPy with high conductivity can be achieved using the anionic polyelectrolyte poly(styrene sulfonate) (PSS). RESULTS: High-conductivity PPy with better processability was successfully synthesized by in situ chemical oxidation polymerization using various concentrations of PSS. Elemental analysis results show that the C/S and N/S molar ratios of the PPy fabricated in the presence of PSS are in good agreement with theoretical values for PPy-SO(4). The S/N ratio increases with increasing PSS content, indicating the high doping level for PPy as the PSS content increases. Scanning electron microscopy and high-resolution transmission electron microscopy images show that the fabricated PPy has spherical structures with the average particle size for the pure PPy being about 250 nm and markedly decreasing to 20-40 nm with the addition of PSS. CONCLUSION: The conductivities of PPy synthesized with a PSS/pyrrole monomer weight ratio of 0.25 are about five times higher than that of PPy matrix. These results are perhaps due to the part played by PSS serving as a dopant to be incorporated into the PPy structure to improve the conductivity of the fabricated PPy.

“…Bands at 1215, 1155, 1083 and 1045 cm -1 can be assigned to C-C-C and C-N-H bending, C-N stretch and N-H deformation as typical aromatic ring vibrations of polypyrrole. 55,56 This enhancement, caused by conduction charges, is related to the overall intensity enhancement of the composite as a result of coupling of the vibrational modes with the electronic states of the increasingly abundant charge carriers upon doping. 54 The IR spectra of three PPy/Lig composites ( Figure 2) prepared from solution compositions ranging from 3:1 to 1:3, yield small differences in the resulting spectra.…”

Spectroelectrochemical investigation of redox states in a polypyrrole/lignin composite electrode material

We report spectroelectrochemical studies to investigate the charge storage mechanism of composite polypyrrole/lignin electrodes. Renewable bioorganic electrode materials were produced by electropolymerization of pyrrole in the presence of a water-soluble lignin derivative acting as dopant. The resulting composite exhibited enhanced charge storage abilities due to a lignin-based faradaic processes, which was expressed after repeated electrochemical redox of the material. The in-situ FTIR spectroelectrochemistry results show the formation of quinone groups, and the reversible oxidation-reduction of these groups during charge-discharge experiments in the electrode materials. The most significant IR bands include carbonyl absorption near 1705 cm -1 , which is attributed to the creation of quinone moieties during oxidation, and absorption at 1045 cm -1 which is due to hydroquinone moieties.after the discovery of metallic polyacetylene by Shirakawa, McDiarmid, Heeger, et al. 10 A strong interest in the development of new storage devices emerged at this time. The benefits of conductive polymers are their high electrical conductivity, processability, low cost and electrochemical reversibility. This is due to the presence of fast charge transfer in the polymeric chain, associated with intercalation/deintercalation of counter-ions during the redox process. 11,12 For many of these reasons, polypyrrole (PPy) seems to be a good candidate for this purpose, as one of the more stable materials, with relatively high theoretical specific capacity 75 mAh g -1 (with dopant) and a specific energy density ranging from 80 to 390 Wh kg −1 . 13,14 However, PPy doped by small, mobile counteranions such as perchlorates, still suffer from self-discharge, from insufficient charge storage density compared to inorganic materials used in secondary batteries, † These authors contributed equally to this work.

“…However, there are some limitations associated with them such as they are inherently insoluble, infusible and difficult to process due to their strong intermolecular interactions. Efforts are being made by the researchers to use them in the preparation of high quality conducting blends with conventional polymers by melt mixing or solution casting . Omatsova et al, have reported the preparation of polyprrole‐based polypropylene (PPy/PP) composites by chemically grafting pyrrole monomers onto PP backbone.…”

“…The composites thus prepared showed the conductivity about seven orders of magnitude higher than in the blends prepared by mechanical mixing of PP and PPy in the same PPy concentration range. The drastic improvement in electrical conductivity for such modified composites could be attributed to improved dispersion of fillers therein .…”

A review on electrically conductive polypropylene and polyethylene

View full text Add to dashboard Cite

Conductive plastics are new generation functional materials with potential application in electronics, space and aviation industries. Polypropylene (PP) and polyethylene (PE) being most common, widely available and cheapest thermoplastic, if made conductive, can be revolutionary in the field of engineering thermoplastics. The article deals with the fabrication of electrically conductive PP and PE for electromagnetic interference/ radio frequency (EMI/RF) shielding applications and protection against electrostatic discharge (ESD). It reviews different fillers used by researchers to fabricate conductive PP and PE, several factors that affect the electrical conductivity of thermoplastic composites and various processing methods that can be adopted to prepare such composites. It exhaustively covers the preparation of such conductive composites, the processing methods involved therein, and the electrical properties of the end material. Emphasis has been given to comprehend the percolation threshold and means to reduce the latter in order to achieve high electrical conductivity in PP-and PE-based composites at relatively low filler loading.
