STUDIES ON POLYPYRROLE NANOSTRUCTURES

Abstract

In the present work, an attempt has been made to synthesize various nanostructures of polypyrrole (PPy) using MnO2 as a reactive template. This approach exploits the possibility of MnO2 morphologies and its versatility as a sacrificial template. These nanostructures have been characterized using scanning electron microscopy; Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction techniques. Particle size analysis shows that the synthesized structure has a size of ~100 nm. These unique architectures of PPy nanostructures may provide an increased electroactive surface area that leads to rapid ion and electron transfer with excellent strain accommodation. Further, the PPy nanostructures can be properly tuned for the practical applications of these materials in electrochemical energy storage and biomedical devices etc.
