Abstract
Recent advances in ultra-fine processing technologies are remarkable. Such as micro machine or magnetic storage device, devices can be smaller and the performance is far advanced. Frictional, capillary and viscous forces are among the most influencing factors in this field of application. In the presence of liquid film, droplet or condensed water from humid air on a surface, a liquid meniscus bridge can be formed between two bodies. The liquid bridge causes a strong interaction heavily influences the operation of micro/nano devices. In this study, we focused on the lateral component of capillarity. The deformation process of the bridge was observed experimentally. And the lateral component of capillary force acting on a body was measured as frictional force. Results shows that an interfacial slip have an important role on the lateral component of capillary force.
