  During the my reseaching period, taking inspiration from the superwetting behavior of natural bubbles at the solid interface (the broken bubble effect of lotus leaves and the bubble pinning effect of rose petals), the mechanism of bubble behavior and interface material properties have been studied, and the concept of gas superwettability of interface material is proposed for the first time. Then, the mechanism of microstructure and chemical composition on the gas wetting behavior was identified. The interface materials with adjustable gas wettability were constructed, which further expanded the research scope of the invasive nature. After revealing the essential relationship between the multi-scale microstructure and chemical composition of the material surface and the macroscopic gas wetting properties, the interface material with synergistic regulation function for the production and release of gas was constructed successfully, and the application of gas interface materials was realized in the field of energy storage and transformation. By choosing the interfaces with different shapes, bubble morphology colud be regulated. Consequently, the interface materials with the function of air bubble directional air transport and directional air collection were prepared and the interface materials with controllable dynamic behavior of droplets were obtained by controlling the morphology of vapor bubbles by high temperature induction.

Investigation fields: The design and performance  of biomimetic intelligent interface materials

(1) Researching on bionic design and performance of drag reduction and antifouling interface:

We carry out theoretical and experimental research on the two major resistance encountered by the underwater vehicle, namely, the viscous friction resistance suffered by streamline (such as ship, torpedo and submarine) and the pressure difference resistance suffered by non-streamline / blunt body (such as depth charge). The gas super lubricating surface is used to form a stable gas layer between the solid interface and the fluid, reducing the fluid adhesion at the solid interface and reducing the viscous friction resistance. After regulating the morphology of gas bubbles and gas films by the microstructures and the surface chemical composition, the blunt body is adjusted from the non-streamline body to the streamline body to reduce the pressure difference resistance. By studying the flow field and pressure distribution, the interaction between droplet and solid interface and the interaction between droplet and liquid clearly define the interaction mechanism between fluid and interface.

(2) Preparing patterned surfaces with different microstructures, or/and different chemical composition and applying them in various fields of interface polymerization and bubble assisting printing.

(3) Preparation and performance research of composite materials, including the interface matching technology of matrix materials and complexes in rubber matrix composite materials and resin matrix composites, and the control and elimination of pore defects in the preparation process of composite materials.

(4) The development of new material synthesis and preparation methods, such as the design of antibacterial, stone prevention, degradable ureteral coated stent.
