“…The study indicates that the addition of a high ratio of TiO 2 nanoparticles lowers the electrical resistivity and consequently increases the electrical conductivity since TiO 2 nanoparticles, a semiconducting substance, is included in the copolymer matrix. Our outcomes are in accordance with our previously reported work and with the work of Yamaguchi and Morisaka . This behavior can be attributed to the core–shell formation of TiO 2 nanoparticles and the pristine PANI‐ o ‐PDA which was already observed in the morphology measurements.…”

The current study establishes the unprecedented involvement in the evolution and production of novel core-shell nanocomposites composed of nanosized titanium dioxide and aniline-o-phenylenediamine copolymer. TiO 2 @copoly(aniline and o-phenylenediamine) (TiO 2 @PANI-o-PDA) core-shell nanocomposites were chemically synthesized in a molar ratio of 5:1 of the particular monomers and several weights of nano-TiO 2 via oxidative copolymerization. The construction of the TiO 2 @PANI-o-PDA core-shell nanocomposites was ascertained from Fourier transform IR spectroscopy, UV-visible spectroscopy and XRD. A reasonable thermal behavior for the original copolymer and the TiO 2 @PANI-o-PDA core-shell nanocomposites was investigated. The bare PANI-o-PDA copolymer was thermally less stable than the TiO 2 @PANI-o-PDA nanocomposites. The core-shell feature of the nanocomposites was found to have core and shell sizes of 17 nm and 19-26 nm, respectively. In addition, it was found that the addition of a high ratio of TiO 2 nanoparticles increases the electrical conductivity and consequently lowers the electrical resistivity of the TiO 2 @PANI-o-PDA core-shell nanocomposites. The hybrid photocatalysts exhibit a dramatic photocatalytic efficacy of methylene blue degradation under solar light irradiation. A plausible interpretation of the photocatalytic degradation results of methylene blue is also demonstrated. Our setup introduces a facile, inexpensive, unique and efficient technique for developing new core-shell nanomaterials with various required functionalities and colloidal stabilities.

“…The nanosized metal oxides were prepared by a simple reduction reaction from their bulk size. The procedure in brief was as follows: 1.0 g of bulk-sized AgNO 3 or V 2 O 5 was dissolved in 100 mL of DD water, and 1 g of NaBH 4 was added under mild stirring conditions at room temperature with nitrogen purging. The addition of NaBH 4 led to the reduction of the bulk-sized material to its nanosized material.…”

“…Various aniline (ANI)-based copolymers have been reported in the literature. For example, ANI has been copolymerized with orthanilic acid, 1 o-phenylenediamine, 2 2-aminoterephthalic acid, 3 tetrafluoroaniline, 4 3-aminophenol, 5 fluorene, 6 xylidine, 7 N-vinyl carbazole, 8 caprolactone, 9 2-aminobenzoic acid, 10 pyrrole, 11 dithipen-2-ylaniline, 12 o-tluidine, 13 p-phenylenediamine, 14 and thymol blue (TB). 15 In a thorough literature survey, we did not found any report on copolymers containing azo dyes, particularly, Congo red (CR).…”

Electrically conducting, water‐soluble fluorescent copolymer nanocomposites were synthesized by a solution polymerization method under different experimental conditions in the presence of CuO and V2O5 nanoparticles. The prepared copolymer nanocomposites were characterized with analytical tools, including Fourier transform infrared spectroscopy, ultraviolet–visible (UV–vis) spectroscopy, and fluorescence emission spectroscopy. The order of copolymerization was determined on the basis of the UV–vis absorption spectra and fluorescence emission spectra. The copolymer–CuO nanocomposite system exhibited the highest electrical conductivity. The scanning electron microscopy image showed the presence of more CuO nanoparticles on the surface of the copolymer. Furthermore, the catalytic activity of the copolymer nanocomposites was tested for the reduction of p‐nitrophenol. All three types of polymer systems exhibited almost the same apparent rate constant values. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46469.

“…Conductive polymers (CPs) have been studied for the replacement of electronic devices, optoelectronics, and semiconductor materials due to their mechanical strength, electrical conductivity, corrosion stability and possibility of both chemical and electrochemical synthesis [1][2][3]. The benzene ring and the π bond are usually present in the polymer, which facilitates electron transport of the polymer and the external environment, thereby making them useful in wide area of applications.…”

Synthesis of poly(o-phenylenediamine) (PoPD) and poly(o-phenylenediamine)-ZnO (PoPD-ZnO) nanocomposites on carbon steel by in-situ polymerization with HCl acid as doping acid Material coating. The composition and structure of PoPD-ZnO nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The corrosion protection ability of polymer coatings in 3.5% NaCl was studied by potentiodynamic polarization curves and electrochemical impedance spectroscopy. It can be seen from the electrochemical corrosion experimental data that PoPD-WPU coating (PWC) and PoPD-ZnO-WPU coating (PZWC) can effectively improve the corrosion resistance of the carbon steel substrate, and the corrosion rate is reduced by 2-3 orders of magnitude compared with carbon steel. The conclusion demontrates that PoPD can effectively extend the service life of carbon steel substrates. In addition, it is advantageous to form a compact and low-defect coating when added nano-particle ZnO, which is advantageous for the POPD film to develop its good barrier property and corrosion resistance.
