Structural Evolution of Complexes of Poly(styrenesulfonate) and Cetyltrimethylammonium Chloride

Structural evolution is tracked as a charged surfactant, cetyltrimethylammonium chloride (CTAC), is titrated into a solution of oppositely charged polyelectrolyte, sodium poly(styrenesulfonate), to form polyelectrolyte−surfactant complexes. At surfactant-to-polymer molar charge ratio [r] less than 0...

Zusammenfassung:Structural evolution is tracked as a charged surfactant, cetyltrimethylammonium chloride (CTAC), is titrated into a solution of oppositely charged polyelectrolyte, sodium poly(styrenesulfonate), to form polyelectrolyte−surfactant complexes. At surfactant-to-polymer molar charge ratio [r] less than 0.5, small-angle neutron scattering of the soluble complexes reveals bound spherical CTAC micelles of radii 21−24 Å, slightly less than for pure CTAC. At such small [r], the number of spherical micelles per chain grows with [r] but never becomes large (
