Polyaniline (PANI)-MWCNT-Zinc sulphide (ZnS) nanocomposites were created by in situ polymerization of aniline in the presence of MWCNT and negatively charged ZnS nanoparticles. The nanocomposites were classified using HRTEM, FTIR, UV-VIS absorption spectroscopy, and photoluminescence (PL) spectroscopy. HRTEM was used to determine the particle sizes of several nanocomposites, which were found to be about 3.21 nm. The introduction of ZnS nanoparticles in PANI-MWCNT caused a red shift in the band gap, according to absorbance studies. For these samples, the Holstein … Continue reading “Synthesis, Optical and Electrical Properties of PANI-MWCNT-ZnS Nanocomposites”

Conducting polymer (CP), polypyrrole (PPy), and their nanocomposites (NCs) with metal oxide -Fe2O3 (CP/MO) are generated in situ employing various oxidants and dopants while maintaining varied molar percentages of MO with monomers. FTIR is used to characterise the prepared CPs and their CP/MO NCs PPy/-Fe2O3. SEM and TEM techniques were used to investigate their morphology. The creation of CPs and associated NCs is ensured by the presence of identity bonds on FTIR spectrograms. On the surface of CP and its … Continue reading “Detailed Study on the Effect of Oxidant, Dopant and MO Additive Loading on Morphology, Conductivity and Dielectric Constant of 3D Conducting Polymer PPy/α-Fe2O3 Nanocomposites”
