Research Abstract

We have studied the fundamental mechanism of lubrication of liquids and liquid crystals confined between solid surfaces. As a result, we have succeeded at (1) the development of a new shear measurement of liquids confined between solid surfaces, (2) the evaluation and development of an interatomic potential model among an mineral surface and a liquid crystal molecule (6CB), (3) the development of new method of the interfacial structure analysis using a combination between X-ray CTR technique and MD simulations, and (4) understanding the lubricational mechanism of water confined between mica surfaces. These results could contribute to the development of good lubricants.
