Electrical Conductivity and Structural Studies on Polypyrrole Synthesized in
Different Environments

ABSTRACT

Conducting polymers are a special class of polymers which allow electrical conductivity to pass through them. Polypyrrole is a promising conducting polymer with applications in different field of research. In this work, polypyrrole is synthesized in different environments such as variable solvent, oxidants, and oxidant ratio. The synthesized samples were collected and dried in an air oven. They were characterized using advance analytical techniques such as UV-Visible spectroscopy, scanning electron microscopy (SEM), and Fourier transform infra-red (FTIR) spectroscopy. The electrical conductivity of the samples was obtained using a four-in-line DC electrical conductivity meter. All the samples were found to exhibit the characteristic peaks of polypyrrole in their UV-visible and FTIR spectra. The electrical conductivity study reveals their electrically semi-conducting nature.

Key words:  Polypyrrole, DC electrical conductivity, In situ polymerization, Scanning electron microscopy, Fourier transform infrared spectroscopy
