    • 摘要: 仿猪笼草的超滑表面由于可以抵抗多种液体的粘附,具有优异的稳定性与自修复性,受到越来越广泛的关注。而飞秒激光由于其对加工材料的普适性、高精度,以及高可控性,成为仿生超滑表面制备的有力手段。本文以仿猪笼草的超滑表面为背景,以飞秒激光微加工技术为手段。从超滑表面的飞秒激光微纳制备和应用两个方面,概述了超滑表面的微纳制造和应用。针对不同材料,通过对飞秒激光进行调控,实现了在聚合物、硬脆透明材料,以及金属上的超滑表面制备。制备的超滑表面可应用于液滴、气泡操控、生物抗凝、防污和防腐等领域。最后总结超滑表面所面临的挑战。

       

      Abstract: The slippery surface inspired by Nepenthes has received research and industry attentions due to its excellent liquid repellency, stability and self-repair property. The femtosecond laser is a powerful method to prepare the slippery surfaces due to its universality in processing materials with high precision, and high controllability. In this paper, taking the lyophobicity of slippery surfaces as a background, using femtosecond laser mico/nano-manufacturing technology as a method, the development of slippery surfaces by femtosecond laser was summarized from two perspectives, including the femtosecond laser mico/nano-manufacturing and applications of slippery surfaces. By controlling the processing parameters of femtosecond laser, the slippery surfaces could be fabricated on various materials, such as polymers, hard brittle transparent material, and metals. The prepared slippery surface can be applied in the fields of droplet and bubble manipulation, biological anticoagulation, antifouling, and anti-corrosion. Finally, the challenges of slippery surfaces were summarized.
