“…The first step of weight loss is occurred at 50-180°C, which may be due to humidity loss, it is about 10 % weight loss. A slight weight loss happens before 190°C due to the decomposition of oligomers molecules [7,13,21]. The second step of weight loss that occurs between 200 and 400°C attributed to the loss of surfactant dopant.…”

“…The mentioned advantages of PPy lead to wide potential applications in various fields, such as rechargeable and lightweight batteries, drug delivery, membrane separation, supercapacitors, sensors, corrosion protection and electronic and electrochromic devices. The unique properties of metal nanoparticles and conducting polymers result in an increasing motivation in the synthesis of nanocomposite materials containing from finely and homogenously dispersed nanoparticles in conducting polymer matrices [5][6][7]. On the other hand, the metal nanoparticles, such as silver and gold, have attracted much attention currently due to their high conductivity, therefore potential applications in technological fields.…”

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.

“…Polypyrrole (PPy)-noble metal nanocomposites are among the most promising nanocomposite materials, and there is increasing interest in their synthesis, characterization and application. [3][4][5][6][7] Recently, some of the present authors 8 succeeded in the one-step synthesis of sterically stabilized PPy-palladium (Pd) nanocomposite particles by aqueous chemical oxidative dispersion polymerization using PdCl 2 as an oxidant in the presence of a colloidal stabilizer. The synthetic method reported in our previous study has several advantages.…”

The nanomorphology of sterically stabilized polypyrrole-palladium nanocomposite particles synthesized by aqueous chemical oxidative dispersion polymerization has been extensively characterized by transmission electron microscopy (TEM) and smallangle X-ray scattering (SAXS). High-resolution TEM studies revealed that non-spherical nanocomposite particles were produced with a Heywood diameter of B30 nm and also confirmed the existence of palladium nanocrystals with a diameter of 5.4 nm within the particles. SAXS studies on aqueous dispersions of the nanocomposite particles confirmed good colloidal stability and revealed that the average diameters of the Pd nanoparticles and the nanocomposite particles were 5.0 and 23 nm, respectively, which agreed well with the TEM results. Furthermore, their size distributions were revealed by the SAXS technique. The hydrodynamic diameter of the nanocomposite particles determined by dynamic light scattering was larger than those determined by TEM and SAXS, possibly owing to the presence of a hydrated colloidal stabilizer layer on the particle surfaces.

Abstract:Conducting polymers (CPs) have been widely studied to realize advanced technologies in various areas such as chemical and biosensors, catalysts, photovoltaic cells, batteries, supercapacitors, and others. In particular, hybridization of CPs with inorganic species has allowed the production of promising functional materials with improved performance in various applications. Consequently, many important studies on CPs have been carried out over the last decade, and numerous researchers remain attracted to CPs from a technological perspective. In this review, we provide a theoretical classification of fabrication techniques and a brief summary of the most recent developments in synthesis methods. We evaluate the efficacy and benefits of these methods for the preparation of pure CP nanomaterials and nanohybrids, presenting the newest trends from around the world with 205 references, most of which are from the last three years. Furthermore, we also evaluate the effects of various factors on the structures and properties of CP nanomaterials, citing a large variety of publications.
