Micelles formed within coacervates phases can impart functional properties, but it is unclear if this micellization provides mechanical reinforcement of the coacervate whereby the micelles act as high functionality crosslinkers....

The results obtained from Fourier transform infrared study of sodium dodecyl sulfate (SDS) in water and in the presence of styrene/acrylic acid (S/AA) copolymer are presented. The C-H stretching band of the SDS hydrocarbon tail at 2929 cm−1 and the O-H stretching of H2O are sensitive to changes in the SDS concentrations. With the increasing concentration both bands are shifted to lower frequency. A mutual presence of S/AA copolymer and surfactant in the aqueous solution leads to a splitting of the bands due to COO− groups. It is proposed that the splitting is due to interactions between COO− segments of the copolymer and the “surfaces” of micelles through the Na+ or Li+ ions.

AbstractPolypyrrole (PPy) dispersions with high stability were prepared in the mixed aqueous solution comprising an anionic surfactant (sodium dodecyl sulfate, SDS) and a polymeric stabilizer (polyvinyl pyrrolidone, PVP). By choosing proper mass ratios of the surfactant to the monomer, stable dispersions could be obtained owing to the interaction between the two components. The structure, morphology, stability, particle size, polydispersity index and conductivity of the samples obtained from different conditions were investigated. The PPy dispersions prepared from mixed aqueous solutions were much more stable than those from single component solution.
