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

纳米流体的流变学和摩擦学性能成为降低环境载荷和能量损失的重要因素。在本研究中，我们将自己开发的共振剪切法应用于纳米受限液体的性质研究。建立了制备金、银等光滑金属表面的方法。研究了约束液晶在电场作用下的流变学和摩擦学性能。建立了用共振曲线分析黏滑摩擦的方法。我们还开发了复合材料黏附研究仪器和纳米密闭液体的x射线结构分析仪器，以了解密闭液体在密闭空间中的结构。

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.
