| Outline of Final Research Achievements |
To understand gel interface, we need to know its thickness and relaxation time. Distributions of gelator and solvents near a solid surface were directly mapped using confocal Raman microscopy. Completely miscible binary solvents, xylene and octanenitrile, were gelled by 12-hydroxystearic acid. Only at the solid interfaces that could be wetted completely by xylene, xylene existed in excess over a distance of 200 micrometers. The excess concentration depended linearly on the distance from the solid surface and disappeared taking over 3 hours, while octanenitrile and the gelator distributed uniformly. Enthalpic interaction of xylene and the solid surface is responsible for the concentration excess. Both the gel network and the solvent’s cohesive energy are thought to cause the long distance dependence.
