Advancing electrical properties through hybridization: Synthesis, characterization, and doping of poly(m‑aminophenol)/ SnO2 Nanocomposites

This study focuses on the synthesis of novel organic/inorganic hybrid materials by combining the conductive polymer poly (m-aminophenol) (PMAP) with the metal oxide SnO2, with the primary aim of enhancing the electrical properties of the resulting nanocomposite polymer. The nanocomposite is intricately crafted through in situ polymerization of m-aminophenol in the presence of SnO2, incorporating various loading rates (1%, 3%, 10%). Comprehensive characterization of the synthesized materials is conducted using analytical techniques including infrared spectroscopy (IR), UV–Visible spectroscopy, and X-ray diffraction (DRX), confirming the structural integrity of the hybrid materials. Notably, XRD analyses distinctly illustrate the successful integration of SnO2 into the polymer matrix. Conducting an extensive study on the doping of PMAP samples with varying concentrations of SnO2 (1%, 3%, and 10%) reveals a nuanced relationship between dopant concentration and electrical conductivity. The doped polymers exhibit a significant enhancement in electrical conductivity, directly correlating with the concentration of SnO2. This comprehensive exploration offers valuable insights into customizing the electrical properties of hybrid materials for diverse applications.
