Poly(4-Chloromethyl Styrene-g-4-Vinylpyridine)/TiO2 Thin Films as Templates for the Synthesis of Polypyrrole in the Nanometer-Sized Domain

Abstract

Poly(4-chloromethyl styrene-g-4-vinylpyridine)/TiO 2 ((PCMSt-g-P4VP)/TiO 2 ) nanocomposite was employed as template for the synthesis of polypyrrole (PPy) in the nanometer-sized domain using a chemical oxidation polymerization method. For this purpose, at first P4VP chains of (PCMSt-g-P4VP)/TiO 2 nanocomposite were complexed with Cu 2+ ions in toluene as the solvent and then converted to thin film by dip-coatings on a glass slide. Thereafter PPy was selectively synthesized in the P4VP core containing Cu 2+ ions, by soaking the thin film in methanol solutions of pyrrole monomers. The synthesized templated PPy species were studied using scanning electron microscopy and Fourier-transform infrared spectroscopy. The optical properties of the products were obtained using UV-Vis spectroscopy and the electrical conductivity of the samples was measured using samples in which the conductive materials were sandwiched between two Ni electrodes at room temperature. Also, using the electrochemical method, synthesis of PPy onto (PCMSt-g-P4VP)/TiO 2 templates was confirmed under cyclic voltammetric conditions on the surface of the working glassy carbon electrode (GCE).

Electrically Conductive Polystyrene/Polypyrrole Nanocomposites Prepared via Emulsion Polymerization

“…Conductive organic polymers have become a popular basic material for a wide range of potential advanced applications [1][2][3][4][5] . Among conductive organic polymers, polypyrrole (PPy) has been extensively studied due to its high conductivity, low cost, ease of synthesis and good environmental stability.…”

One‐Step Synthesis of Conductive BNC/PPy·CuCl2 Hybrid Flexible Nanocomposites by In Situ Polymerization

“…As can be seen, this band has been observed in many samples of polypyrrole both chemically and electrochemically polymerized. is band corresponds to the overoxidation of the C�O band of pyrrole, which influences its conductivity [25][26][27]. Figure 3 shows X-ray diffraction spectra of pure bacterial nanocellulose and BNC/PPy•CuCl 2 nanocomposites polymerized with different Py concentrations and molar ratios.…”

Self-Assembled Glucose and Thermo Dual-Responsive Micelles of an Amphiphilic Graft Copolymer

“…Adding to hydrophobicity of the whole copolymer was that hydrophobic characteristic of the PBA groups. Therefore, the copolymer had a high tendency to aggregate into micelle through self-assembly [38,39]. At 33 C, the D h of micelles decreased and the distribution narrowed down, indicating that primary aggregation had been finished at this temperature.…”
