In this study, Polyaniline-ignimbrite (PAN-IB) which is a novel nanocomposite material consisting of electrically conductive Polyaniline (PAn) polymer and Ignimbrite (IB) natural insulating material was synthesized chemically using KIO3 as a radical initiator in aqueous media with conventional radical polymerization method. The synthesized nanocomposites including ignimbrite with various monomer-ignimbrite percentages were monitored with scanning electron microscopy (SEM) and structural characterizations were examined with FTIR spectroscopy. Thermogravimetric analysis (TGA), particle size analysis with dynamic light scattering, magnetic susceptibility and conductivity measurements were also examined for all synthesized composites. With making a composite with aniline, the conductivity of ignimbrite (3 × 10-7 Scm-1) reached to 2.7 × 10-5 Scm-1. However increasing the ratio of monomer which is added to ignimbrite did not make a significant change on conductivity of the resulting composite.
