“…The peak at about 610 nm has been shifted to lower wavelengths of *558 nm which may be due to the n-p* transitions of quinine-imine groups [28]. These results showed that PAni was completely converted from emeraldine salt to the emeraldine base form by the deprotonation of PAni with NH 4 OH [29].…”

An efficient methodology of polyaniline-TiO 2 nancomposite (PAniTNC) was developed through various proportions of ceramic added by chemical polymerization at room temperature. The chemical polymerization reactions were carried out using potassium perdisulphate as an oxidizing agent. The particle size of PAniTNC was found in the range of 8-15 nm as analysed by transmission electron microscopy. The Ti-O characteristic stretching bands at 630 and 558 cm-1 , indicating the presence of TiO 2 in polyaniline matrix was confirmed by fourier transform infrared spectroscopy. The characterization of the nanocomposite crystalline shape was carried out using X-ray diffraction method. Thermogravimetric and differential scanning calorimetry analyses indicate high thermal stability. SEM analysis showed mixed granular nature of the polymer-ceramic nanocomposites. EDX analysis shows the presence of Ti, C and N in composites. Cyclic voltammetric studies exhibit good adherent behaviour on the electrode surface at pH 1.0. It reveals the presence of oxidation peak at 0.417 V and reduction peak at 0.285 V. It has been observed that PAniTNC-modified GCE has good oxygen reduction ability, and also enhances methanol reduction.

“…2.3. In Situ Polymerization.The typical conducting polymers such as PANI and polypyrrole and their composite systems have been extensively studied, thanks to their controllable electric conductivity and other attractive advantages such as bulk processability and dielectric characteristics[45][46][47]. PANI particles or PANI based hybrids with different morphologies have been extensively studied because of their low cost, facile fabrication, and attractive environment stability.…”

Graphene oxide (GO) based composite systems have been fabricated and investigated as a novel electroresponsive electrorheological (ER) dispersed phase because of their proper electrical conductivity and polarizability for their ER application, in addition to graphene composites. This paper briefly reviews mechanisms of the fabrication of various graphene and GO based composites and their critical ER characteristics including flow curve, yield stress, and dynamic properties measured using a rotational rheometer. Relaxation time and achievable polarizability from dielectric analysis using a LCR meter are also discussed.

“…Therefore, this is another proof of the formation of the SSARs. On the other hand, T d2 obtained for the SSARs was higher than those obtained to reactive blends of unsaturated polyester resins/St ( T d lower than 390 °C) and a vegetable‐oil‐based hyperbranched polyester‐St copolymer whose T d1 value was 410 °C …”

Waterborne star‐shaped styrene‐alkyd resins (SSARs) were synthesized from a branched alkyd resin (AR) and styrene (St) by miniemulsion polymerization. SSARs are an environmentally friendly material. The ratio of AR to St for obtaining SSARs was as follows: 50:50 (SSAR1), 60:40 (SSAR2), 70:30 (SSAR3), and 80:20 (SSAR4). The conversion percentage was directly proportional to St used, and was higher than 94.0 %. Infrared analysis and protonic nuclear magnetic resonance revealed the reaction between AR and St. The synthesis process also leads to the formation of polystyrene and its concentration increases with the concentration of St. The values of the reacted double‐bond fractions were higher than 17.80%. The SSARs drop size was bigger than the particle size. The miniemulsion colloidal stability was good at room temperature. The SSARs zeta potential was between −55 and −90 mV. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48386.
