Polyaniline (Pani) has been attracted attention owing to many advantages: the monomer has low cost and the polymerization method is relatively simple. However, its large-scale commercialization is difficult due to its poor processability and thermal stability. To overcome these problems, many researches on the improvement of processability have been widely investigated, such as preparation of conductive polymer composites or blends in thermal processing. In this study, Ag/re-doped Pani nanoparticle composites were prepared. Pani nanoparticles were polymerized from micellar polymerization. Using ‘doping-dedoping-redoping’ method, Pani re-doped by mercaptosuccinic acid (MSA) was prepared, and silver nitrate solution was added in this material. FT-IR and UV-vis spectroscopy confirmed Pani formation. The thermal characteristics were studied using DSC and TGA. We investigated the effect of thermal treatment on the conductivity and the effect of thermal stability on surface resistivity. |
