Abstract
The effects of the addition of various carboxylic acids on the formation of AOT-reverse micelle clusters have been studied by quantitative analysis of their percolation phenomena. The results were compared with those of various alcohols based on the functional groups, namely, the hydrocarbon group, hydroxyl group, halogen substituents, and carboxyl group. Among these groups, the hydrophobic hydrocarbon group and halogen substituents suppressed the formation of micellar clusters, depending on their chain number or species. However, the hydrophilic carboxyl and hydroxyl groups enhanced the formation of micellar clusters. Furthermore, the effect of a hydroxyl groups on the formation of micellar clusters was stronger than that of carboxyl groups. These results can be explained by the additive contribution of each carboxylic acid and alcohol molecule, and they can be interpreted as a simple correlation based on the accessible surface area (ASA). These results suggest that the formation of AOT-reverse micelle clusters by the addition of carboxylic acids and alcohols can be explained by the hydrophobicity of the molecule, as well as by the formation of micelle-like structures with both carboxylic acid and alcohol molecules.
