Advancing electrical properties through hybridization: Synthesis, characterization, and doping of poly(m-aminophenol)/SnO₂Nanocomposites

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.
