Issue Date: | 25-Sep-2009 | Journal Volume: | 1126 | Start page/Pages: | 163 | Source: | Materials Research Society Symposium Proceedings | Abstract: | In this study, polyaniline (PAni) composites were prepared from in situ polymerization of aniline monomers dispersed in block polyelectrolyte aqueous solution. The block polyelectrolyte, poly(styrene-block-sulfonated hydroxystyrene) (PS-b-sPHS), was synthesized through anionic polymerization and sequential analogous chemistry. The block polyelectrolyte played the role as the template to direct the morphology of PAnilblock polyelectrolyte composites and they were also served as dopants simultaneously to enhance the electric conductivity of the PAni/block polyelectrolyte composites. Variables affecting the morphologies, the compositions and the conductivities include the concentrations of the block polyelectrolyte aqueous solution and the reaction time. The growth mechanism of the PAniIPS-b-sPHS composites was also investigated. |
