Abstract
Nanocomposites are advanced materials obtained by combining two or more solid phase, one which having at least one dimension in nano scale range. In this study conducting elastomer nanoparticles are prepared by solution doping method using a Lewis acid as dopant. Subsequently, these nanopowders are encapsulated by an intrinsically conducting polymer, polypyrrole by chemical root method to obtain rubber polypyrrole nano composite. Highly transparent conducting films are obtained by dispersing these nano composite in ethanol using poly vinyl pyrrolidone as a stabilizing agent. The I-V characterization studies satisfies the electrical conductivity of the composite. The UV-Vis spectroscopy gives an insight into the optical absorption properties of the composite. Further composite film characterizations satisfy the requirements of transparency and surface morphology for simple optoelectronic applications. The SEM picture shows that the conducting elastomeric nanoparticles are effectively dispersed in the PVP matrix..
