Abstract
The present invention relates to hybrid electrically conducting systems comprising a matrix of a conducting polymer (polyaniline—PANI), and highly conducting carbonaceous nanoparticles, e.g., carbon nanotubes (CNT) or graphenes. The PANI/carbon nano-composites are prepared by a novel process comprising the steps of (a) polymerizing aniline and carbonaceous nanoparticles by inverse emulsion polymerization conducted under sonication, so as to obtain PANI/carbon nano-composites; (b) dc-doping the PANI/carbon nano-composites obtained in step (a); (c) re-doping the PANI/carbon nano-composites obtained in step (b); and (d) forming a film from the re-doped PANI/carbon nano-composites. The PANI/carbon nano-composites are used for the preparation of thin, transparent, and conductive films which can be applied to a variety of substrates and used for commercial applications.
