Preparation of three-component conducting polymer composite using nucleate doping technique

Abstract

This paper reports a new route for the preparation of conducting network in insulating polymer matrix. In existing techniques solubility of conducting component is an essential condition. Reported technique facilitates making composite of conducting polymer, which is insoluble in normal solvents, with percolation threshold of 0.5 wt%. <span style="mso-ansi-language:EN-IN">Mechanism of formation of the three component hybrid may be described as when silica <span style="mso-ansi-language: EN-IN">which acted as seed is dispersed in insulating polymer, the in-situ polymerized conducting polymer having high aspect ratio is grown over the silica surface connecting each other and making a continuous network. The star like growth of the conducting polymer can be seen under optical microscope.
