Effect of hydrophobic chain length of surfactants on enthalpy-entropy compensation of micellization
Article Abstract:
Various alkyl chain lengths of several nonionic surfactants were used to investigate the effect of hydrophobic chain length of surfactants on enthalpy-entropy compensation of micellization. The temperature of minimum critical micelles concentration for both ionic and nonionic surfactants was found to increase with the decrease of the hydrophobicity of surfactants. The enthalpy-entropy compensation plots were found to be linear. All the compensation lines for surfactants in a homologous series were observed to be almost parallel to one another.

Interfacial and thermodynamic properties of SDBS-C12E10 mixed micelles in aqueous media: effect of additives
Article Abstract:
A study was conducted to analyze the interfacial and thermodynamic characteristics of SDBS/C12E10 mixed system in an aqueous solution during the presence of additives. Surface tension data and conductivity measurements were utilized to obtain the critical micelle concentrations. Experimental results indicated that the overall micellization process was exothermic. Findings also showed that the entropy of micellization was positive.
