제목 Investigation of interaction between sodium dodecyl sulfate and cationic polymers and solubilization into their aggregates
초록 Solubilization property of the aggregates composed of SDS and a cationic polymer (polydiallydimethylammonium chloride) was investigated. From the binding isotherm, the increasing free SDS concentration above the cac was clearly confirmed and used to calculate the Gibbs free energy change of solubilization. The Gibbs energy change for the solubilizates decreased with increasing temperature and with increasing alkyl chain length. The Gibbs energy decrease per CH2 group was promoted with increasing temperature and was larger in magnitude than that for micelles of single surfactant systems. From the values of ΔH0 and TΔS0, the solubilization of alkylbenzenes into SDS/PDADMAC was found to be entropy-driven.
