Abstract
We investigated the structure of poly(allylamine hydrochloride) (PAAMHCl) g el-sodium dodecylbenzenesulfonate (SDBS) surfactant complexes using small-a ngle X-ray scattering. PAAMHCl gels were prepared by using N,N ' -methylene bisacrylamide as a cross-linking agent. These gels were complexed with SDBS below a critical micelle concentration of the surfactant. The gel-surfacta nt complexes (GSC) exhibited lamellar structures with an interlayer spacing of 35 Angstrom which is less than twice the length of the stretched SDBS m olecule. The effect of ionic strength on the formation and the structure of GSC were investigated. The complexes were found to be highly stable in pre sence of salt solutions. (C) 2001 Elsevier Science Ltd.
