Preparation of microcapsules of strong polyelectrolyte couples by one-stepcomplex surface precipitation

Full Paper: Polyelectrolyte microcapsules are fabricated by a one-step surf ace precipitation and by a layer-by-layer technique an decomposable colloid s. The ternary solvent water/acetone/sodium bromide is adjusted properly ke eping dissolved simultaneously the strong polyelectrolytes sodium poly(styr ene sulfonate) and poly(vinyl benzyl trimethylammonium chloride). Microcaps ules are characterized by confocal laser scanning microscopy and scanning f orce microscopy. The capsules are dissolvable in the ternary solvent. Other dissolved strong polyelectrolyte couples and template-free preparation pat hways are suggested.
