Stable polyaniline (PAn) aqueous dispersions were obtained using poly(vinyl alcohol)(PVA) as steric stabilizer via dispersion polymerization. The size of PAn was influenced by the steric stabilizer(PVA) concentration
monomer(aniline) concentration
temperature and stirring state. The stable PAn particles with size of 100nm~200nm in diameter were composed of original particles whose size in diameter was about 20nm. The enhanced aggregation of PAn particles was prevented by the presence of PVA which absorbed on the surface of PAn particles via physical interaction
