Preparation, Characterization and Thermal Studies of Polypyrrole - Gold Nanocomposites

Background: Understanding nanocomposites' morphological characteristics is important for explaining their properties and their usefulness. Method: In this review, we present the method for interfacial synthesis of polypyrrole and its gold nanocomposites with varying concentrations of polymer. The bonding involved in the nanocomposites is understood from Fourier transform infrared spectroscopy and X-ray diffraction studies confirmed the crystalline nature of the particles. Result: Scanning electron microscope and transmission electron microscopy studies showed that the spherical and globular nature of the particles is mutually connected to form nanocomposites compared with virgin polymer. Conclusion: Catalytic behavior of gold nanoparticles in polymer composites is observed from the thermal analysis.
