Soluble complexes of sodium poly(isoprene-b-methacrylate) micelles with cationic surfactants in aqueous media.

摘要: Water-soluble complexes between sodium poly(isoprene-b-methacrylate) (NaIMA) amphiphilic block copolymer micelles and two cationic surfactants with different hydrophobic tail lengths, namely, dodecyltrimethylammonium bromide (DTMAB) octyltrimethylammonium (OTMAB), were prepared by mixing individual aqueous solutions of copolymers surfactants. The characterized in terms size, overall charge, micropolarity dynamic light scattering, ζ-potential measurements, fluorescence spectroscopy. Properties the systems investigated as a function surfactant concentration type state initial solutions, well temperature. Experiments reveal complexation at coronal poly(methacrylate) (NaMA) chains, followed an increase mass decrease size micelles. Complexation was observed when DTMAB starting higher than surfactant...
