演讲摘要:
生物微/纳米结构都包含了下一代智能人造材料和设备的目标。例如,荷叶表面的纳米结构使叶片超疏水,含有收集的昆虫和灰尘的水滴将滚落,从而保持叶片表面干净。本演讲总结了飞秒激光微制造技术在生物感应智能结构开发方面的最新进展,重点讨论了可控、仿生和可切换润湿表面,以及它们在生物学、微流体和工业中的应用,所有这些都展示了这种能力 激光微细加工生产各种多尺度结构及其适应多种材料。这个快速发展的领域目前的挑战和未来的研究前景也在讨论之中。 Biological micro/nano-structures all comprise the goals for the next-generation smart artificial materials and devices. For examples, nanostructures on the surface of the lotus leaf render the leaves superhydrophobic, and the droplets of water containing the collected insects and dust will roll off, and so maintain a clean leaf surface. This presentation summarizes the recent progress in the development of bioinspired smart structures via femtosecond laser microfabrication, with a focus on controllable, biomimetic, and switchable wetting surfaces, as well as their applications in biology, microfluidic, and industry, all of which demonstrate the ability of laser microfabrication in producing various multiscale structures and its adaptation in a great variety of materials. The current challenges and future research prospects of this rapidly developing field are also being discussed.
