“…The first stage weight loss at 120 °C can be ascribed to the water molecules loss for all the prepared polymers. The second stage within the temperature range of 120–350 °C is related to the removal of CO 2 molecules from the PANAA and PAA . The third stage with weight loss was in the range 350 to 700 °C, the degradation of the polymer chains occurred which corresponds to the thermo‐oxidative degradation of the polymer chains.…”

Oxidative polymerization of aniline, anthranilic acid, and aniline‐co‐anthranilic acid by potassium dichromate Cr(VI) as an oxidant in acidic medium was investigated. In this study, the polymerization process of aniline, o‐anthranilic acid as well as aniline/o‐anthranlic acid using K2Cr2O7 produced, coordinated Cr(III)/polyaniline (PANI), Cr(III)/polyanthranilic acid (PAA) and Cr(III)/poly aniline‐co‐anthranilic acid (PANAA). The mechanism of polymerization reaction in the presence of dichromate was hypothesized. The precursor chromium doped polymers were characterized by TGA, FT‐IR, UV‐visible, XRD analyses. Cr2O3 nanoparticles size were determined using TEM analysis. The calcinations process of synthesized chromium doped PANI, PAA and PANAA yields Cr2O3 nanoparticles 26%, 31%, and 34% wt. respectively. Rhombohedral phase of Cr2O3 particles in the range from 33 to 61 nm was produced from chromium/polyanthranilic acid (PAA) and chromium/poly(aniline‐co‐anthranilic acid) PANAA. UV‐ visible analysis showed that optical band gaps (Eg) of doped poly aniline and its derivatives are in the range from1.55 to 1.80 using Tacu's law. The band gap values reveal that the doped chromium emeraldine base can be used as semiconductor materials. Copyright © 2016 John Wiley & Sons, Ltd.

“…Given that the surface to volume ratio is large at the nanoscale, the addition of nanoparticles can influence the thermal, electrical, optical and dielectric properties of the polymer. For example, incorporation of Al 2 O 3 nanoparticles results in high conductivities of nanocomposites [12], and polymerization of TiO 2 [13] or TiC nanoparticles produces electroactive polymers [14]. Good electrochemical response was observed for polymers grown into Montmorillonite-Cu [15] or MontmorilloniteNa [16].…”

The main objective of this study was synthesis of CuO nanoparticles using extract of Galeopsidis herba and were characterized by UV-Vis spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), SEM with EDS profile and transmission electron microscopy (TEM) analysis. SEM images confirmed that synthesized nanoparticles were spherical in nature. EDS profile confirmed the signal characteristic of cooper and oxygen. All the analyses revealed that synthesized CuO nanoparticles were 10 ± 5 nm in size. The antioxidant behavior of synthesized CuO nanoparticles was evaluated by scavenging free radicals of 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH). The DPPH scavenging activity was monitored using UV-Vis spectrophotometer. The synthesized CuO nanoparticles presented very good catalytic activity in the reduction of malachite green.

“…Novel advances in polymer engineering have certainly increased the investigation of nanostructured CPs [18,19]. A new challenge in this area of nanotechnology is the capability to synthesize relatively small monodispersed CPs nanostructures, and their composites with metal oxide nanoparticles that have multifunctional properties [11,[20][21][22][23].…”

The goal of this study is to synthesize, characterize and investigate some physicochemical properties of conductive polyaniline-g-polystyrene/Fe 3 O 4 (Fe 3 O 4 /PSt-g-PANi) nanocomposites. For this purpose, initially, Fe 3 O 4 nanoparticles were synthesized by a co-precipitation method. Then, the desired nanocomposite was synthesized in two steps. First, the atom transfer radical polymerization (ATRP) of styrene was performed using an ATRP initiator attached to the surface of Fe 3 O 4 nanoparticles, followed by functionalization of the Fe 3 O 4-PSt with amine groups (-NH 2). Second, surface oxidative graft copolymerization of aniline was accomplished using the-NH 2 moieties on the Fe 3 O 4 /PSt-NH 2 as the anchoring sites. The prepared materials were characterized by various instruments, including TEM, SEM, TGA, EDX, FT-IR, XRD and conductivity measurements. The results indicated that the synthesized conductive polymer/Fe 3 O 4 nanocomposites had higher electrical conductivity and thermal resistance than those of the corresponding homopolymers.
