| Anilinium dodecyl sulfate (DS-AN) was obtained from aniline and sodium dodecyl sulfate (SDS). Critic micellar concentration (cmc) of the salt was determined by electrical conductimetry. This technique showed that the change of counterion, sodium by anilinium, induced the reduction of cmc with respect to their conventional counterpart, SDS. Afterwards, DS-AN was used as reactive surfactant (surfmer) in the synthesis of polystyrene / polyaniline core-shell conductive composites. The latexes obtained were stable, which indicated that DS-AN followed the mechanism implicated in traditional emulsion polymerization. Polyaniline synthesis was successfully performed by adding more DS-AN as the monomer and APS as the oxidizing agent, no acid addition was required in this procedure. The composite presented conductivities in the order of 10-4 to 10-3 S/cm. | |
