内容简介:
Nature such as plants, insects, and marine animals uses three-dimensional (3D) micro/nano-textured surfaces with tailored surface wettability and mechanical pliability in their components (e.g., leaves, wings, eyes, legs, and skins) for multifunctional purposes such as self-cleaning, low-friction, anti-fouling, anti-icing, and anti-reflection, with great energy efficiency. As scientific quests and engineering applications reach down to such a nanometer scale inspired by the nature, there is a strong need to fabricate 3D nanostructures with good regularity and controllability of their pattern, size, and shape. In many applications, furthermore, the nanostructures are not useful unless they cover a relatively large area and the manufacturing cost is within an acceptable range. The first part of this presentation will introduce effective 3D nano-patterning and fabrication techniques to create well-regulated nanostructures over a relatively large substrate area of various types of substrate materials including ceramics, metals, and polymers. Such large-area 3D nanostructures with tailored structural dimensions and geometries can open new application possibilities in many areas. The rest of the talk will present a few examples of the applications using the 3D nanostructures, such as hydrodynamic friction reduction, anti-biofouling, anti-icing, anti-corrosion, and anti-reflection.
