Nano-rheology and Nano-tribology of liquids confined between solid surfaces

纳米约束液体的流变学和摩擦学特性是降低环境负荷和能量损失的重要因素。本研究中，我们提出了共振剪切法，并将其应用于纳米受限液体性质的研究。建立了制备金、银等光滑金属表面的方法。研究了电场作用下受限液晶的流变学和摩擦学性能。建立了通过共振曲线分析粘滑摩擦的方法。我们还开发了用于研究复合材料粘附的仪器以及纳米受限液体的X射线结构分析，以根据受限空间中的结构来了解受限液体的性质。

Rheological and tribological properties of nano-confined liquids are becoming important key factor for lowering the environmental load and energy loss. In this study, we advanced resonance shear method, which have been developed by us, and applied for investigating the properties of nano-confined liquids. The method to prepare the smooth metal surfaces such as gold, silver, was established. The rhelogogical and tribological properties of confined liquid crystal under the electric field were investigated. A procedure to investigate the stick-slip friction by the analysis of resonance curve was also established. We have also developed instruments for the study on adhesion of composite materials as well as the X-ray structural analysis of nano-confined liquids to understand the property of confined liquid based on their structures in confined space.
