Abstract:
In a chemical oxidative seeded polymerization system of aniline using the polystyrene seed parti cles p retreated by emulsifier ormodified by copolymerizing with acrylic acid, colloidally stable core-shell polystyrene /polyaniline composite particles were p repared. For the influences on the structure and mor phology of the composite particles, the factors including kinds and amount of the emulsifier, weight ratio of aniline and polystyrene seed, and the surface modification of the seed particles were discussed. The size and morphology for the resulting polystyrene /polyaniline composite particles were analyzed by means of transmission electron microscopy, dynamic light scatteringmethod and infrared absorp tion spectrum. It was p roved that the core-shell polystyrene /polyaniline composite particleswith perfect shell and even sur face can be obtained as p retreating the seed particles using tween - 40 and adop ting a lowerweight ratio of aniline and seed particles, ormodifying surface of the polystyrene particles bymeans of copolymerization of styrene and a little amount of acrylic acid.
