Synthesis and characterization of polypyrrole composites: Optimization strategies for tailored material qualities and enhanced applications

Abstract

This study aims to investigate the synthesis and characterization of polypyrrole (PPy) composites using various reactants, with a focus on optimizing synthesis conditions to achieve desired material qualities. The objective is to explore the influence of temperature, reaction time, concentrations, and ratios on the structural and electrical properties of the produced composites. The synthesis process involves the oxidative polymerization of pyrrole employing different metal salts (FeCl3 and Iron (III) Tosylate) and a polymeric dopant (PSS). Material analysis is conducted using X-ray Diffraction (XRD) and UV-Visible Spectroscopy techniques. XRD patterns reveal distinct crystal planes and orientations in multiple composites, providing valuable insights into their structural organization. UV-Visible absorption spectra exhibit electronic transitions at varying wavelengths, elucidating the optical characteristics of the materials. Precise control over synthesis conditions significantly influences the shape, crystallinity, and electronic properties of PPy composites. Systematic optimization leads to tailored properties, enhancing their potential applications in sensors, actuators, and energy storage systems. This research contributes essential knowledge for the systematic advancement and improvement of PPy composites, facilitating progress in materials science and technology. In particular, the investigation of the PPy-La2O3 composite presents novel insights into its structural and optical properties, expanding the understanding of this material system.
