The formation of weak polyelectrolyte films on spherical particle has recently interested in because such thin coatings allow novel material properties to be tunable by PH and salt adjustment of the polyelectrolyte deposition conditions. To de this, we choose the carboxylated PS as probe and the weak polyelectrolyte, poly(allyamine hydrochloride), (PAH) as matrix. The diffusion studies of carboxylated polystyrene particles in PAH solution as a function of concentration and PH was performed using dynamic and static light scattering. We found Carboxylated PS had the aggregate structure in dilute DI-water through guiner plots of static light scattering study. The fully charged PAH in PH 3 solution acted as stabilizer of PS aggregates so that the decay time profile decreased while the partial charged PAH in PH 10 solution operated as just absorbent so that the decay time profile increased. |
