Polystyrene latex particles were swollen with aniline and subsequently exposed to ammonium peroxydisulfate solution. The polyaniline membrane was produced at the particle interface and separated both reactants. The electrons from aniline monomer are transferred to oxidant molecules through conducting polyaniline membrane. The aniline and peroxydisulfate thus react without the need to physically meet. Polyaniline gradually penetrated inside latex particle, in contrast to core-shell morphology obtained in classical coating of latex particles with polyaniline.
