Micro-nano hierarchical bioinspired surface can possess new functions by the regulation of micro-nano hierarchical surface structure and material characteristics.  It has various potential applications in the fields of mechanical engineering, precision medical devices, energy and other fields.  However, since gas and liquid generally exist between the contact interface, their behavior is extremely complex and greatly affects the surface function. To discover the law of dynamic behavior of interfacial liquid and their influence on surface function is very necessary for the innovative design and manufacturing of bioinspired hierarchical surface. This speech will focus on (1) the functional strategy and fabrication approach of micro-nano hierarchical bioinspired surface, and (2) the progress in the study of dynamic liquid behavior on the micro-nano hierarchical surface.  The speech will mainly introduce the structural characteristics of natural biological sample, the unique dynamic behavior of interfacial liquid and its examples of potential applications. The speech emphasizes on the unique strategy of biological slippery and anti-wet slippery function, and its application in the fields of medical devices and aerospace.
