Ultrafast laser inducing of nanostructures: advances and applications

演讲课题:Ultrafast laser inducing of nanostructures: advances and applications

演讲摘要:

The nature evolution inspires magic functions induced by the micro-nano hierarchical structures, the nanostructures create unique functions typically like adhesion/friction/wetting presented by gecko feet, butterfly wings, fish scales, lotus leaves, and rose petals. To understand the nature secrets on functional nanostructures on typical animals and plants and then to fabricate biomimetic synthetic architectures to bring about improved functions that can even surpass those found in nature, is one of the attractive topics in past decades. Ultrafast laser is well known as a marvelous tool for micro-nano structure fabrication. Due to the diffraction limit, however, its capability to form nanostructures is somewhat limited while it is very capable for fabricating designable microstructures. We report here our focused research in recent years to induce various nanostructures, like nano-ripple, nano-cauliflower, nano-villus and nanowires in metallic engineering materials. We then explore the nanostructure functions available in nature and surpass in nature, such as superhydrophobicity, superhydrophilicity, directional wetting, self-clean, anti-reflection, structure color, and high sensitivity. We finally report some typical applications of these functional nanostructures including self-clean surfaces, anti-icing, solar energy utilization, water splitting, lithium cell and super-capacity etc..
