| Research Abstract |
By combination of a total reflection prism and a rotary rheometer, we developed a novel apparatus for the in-situ observation of the frictional interface between gel and glass. By using the apparatus, the formation process of the lubrication layer under gel frictional phenomena was successfully observed. Further, by altering the surface properties of gels (elastic modulus and surface roughness), the change in the lubrication layer was studied. The formation process of the lubrication layer depends on the thickness of gels.
