Abstract
The cationic polystyrene and crosslinked polystyrene latexes synthesized by emulsifier-free emulsion polymerization method functions as seeds and polyaniline grows on the polystyrene/crosslinked polystyrene seeds. Thus, the conductive polyaniline–coated polystyrene core-shell latexes were synthesized. The coated morphology and latex particle were observed by SEM,TEM, and diameter analyzer .The chemical structure and thermal analysis were studied by the FTIR, DSC. Three types of conductive films (polystyrene-polyaniline , crosslinked polystyrene-polyaniline, and the blends) were made by casting and heating the latex particles above the glass transition temperature. The film formation is observed by SEM. Moreover, the conductivity of conductive films were degraded in different temperatures and environments. Relations between the conductivity and the characteristics of core material were studied.
