Title of Speech: Micro-nano Scale dynamic behavior on hierarchical surface and its surface function mechanism
Abstract: With high speed development of micro-nano-characterization, and micro-nano fabrication, novel hierarchical structure and surface function have been found in the duration of the natural cognition. Fortunately, creative inspiration can be gotten from nature and it is an effective way to solve the problems of major engineering. Aiming at the important interface problems encountered in the field of aerospace and precise medical treatment such as anti-icing and anti-slipping, systematical characterization on unique natural biological wet surface (tree frog, Nepenthes peristome) were conducted. Their underlying functional mechanisms were investigated to make clear the relationship between hierarchical structure and interfacial liquid film. Novel phenomena of continuous directional liquid spreading, ultrafast liquid transport and uniform liquid spreading were discovered on specific micro-nano hierarchical surface. These novel interfacial liquid adjusting mechanisms result in unique surface function such as the wet-slipping and anti-slipping. The design principle of bio-inspired anti-slipping and slippery surface were proposed. On basis of surface function mechanism of natural biological surface, we developed anti-icing coating for airplane and bio-inspired medical device for precision medicine, whose efficiency were also validated in practical applications.
