Based on bioinspired concept, the multi-level structured surfaces can be fabricated to investigate the low-temperature water repellency and anti-icing materials,which is significant to decrease the ice damage on aerospace vehicle or power lines and so on. This project will break through the limitation of traditional materials on ice-phobicity, bioinspired gradient-integrated materials with low-temperature water repellency and anti-icing functions will be intent to be investigated based on biomimetic concept of water repellency
mechanism from biological multi-gradient structures. The polymer and organic/inorganic composite materials will be selected to fabricate the smart multi-structures that are easy to induce the shedding-off of water condensed droplet and ice crystalline from the as-fabricated surfaces via the multi-techniques such as physical, chemical, nano-technological and so on. It will be further excepted to fabricate the light and flexible composite-structures and intelligent micro-/nanostructure gradient surface, to further obtain the performance parameters of robust low-temperature and anti-icing properties under ultra cold and humidity surroundings. A main route based on the dynamic controlling of ultra water repellency and ice-phobicity on bioinspired gradient surfaces is to reveal the repellency-related relationship of ice-crystalline and interfaces under different temperatures, and also to reveal essence at micro-/nano-level of icing delay time on the surfaces, to research the key factors of the adhesion, ultra-repellency, extreme shedding-off properties, to control carefully the static/dynamic behavior of icing on surface, to reveal the inherent factors between micro-/nanostructure and low-temperature/anti-icing, to reveal the micro-level
mechanism of controlling the ice-phobic/anti-icing dependence on multi-structures. This project is significant reference to design the novel materials with anti-icing functions.
