具有所需尺寸和形貌的表面微/纳米结构的可控和易于制造是实现表面超疏水性的关键。超快激光辐照具有非接触、无掩模、可编程和一步工艺等优点，是一种非常灵活和自适应的技术，可在各种固体上制造各种微尺度、纳米尺度和微/纳米多尺度表面结构，从而在其表面实现超疏水性。在这篇专题文章中，从材料、方法和功能化的角度全面综述了我们最近在超快激光实现的多功能超疏水表面的研究进展。本文将讨论通过超快激光处理在不同固体表面上实现超疏水性甚至超两疏性，以及超快激光处理表面从超亲水性到超疏水性转变的潜在机制。从实际应用的角度出发，本文将介绍基于超快激光的超疏水表面微纳米结构的大规模和高性价比制造策略。一个特别的重点将致力于提高结构耐久性和Cassie-Baxter稳定性的超快激光启用超疏水表面。除此之外，还将展示集成表面功能的实现，包括卓越的润湿功能，如水滴的定向收集和超疏水表面，同时具有独特的光学性质。
The controllable and facile fabrication of surface micro/nanostructures with the required dimensions and morphologies is the key to achieving surface superhydrophobicity. With the advantages of being a noncontact, maskless, programmable, and one-step process, ultrafast laser irradiation is a very flexible and adaptive technique for fabricating various microscale, nanoscale, and micro/nanomultiscale surface structures on diverse solids, thus realizing superhydrophobicity on their surfaces. In this feature article, a comprehensive review of our recent research advances on versatile superhydrophobic surfaces enabled by ultrafast lasers is presented from the perspectives of materials, methodologies, and functionalization. The realization of superhydrophobicity and even superamphiphobicity on varied solid surfaces through ultrafast laser treatment and the underlying mechanisms for the wettability transition of ultrafast-laser-processed surfaces from superhydrophilicity to superhydrophobicity will be discussed. For the sake of practical applications, the ultrafast-laser-based strategies for the large-scale and cost-effective fabrication of superhydrophobic surface micro/nanostructures will be introduced. A special focus will be devoted to the enhancement of structural durability and the Cassie-Baxter stability of ultrafast-laser-enabled superhydrophobic surfaces. Beyond that, the achievement of integrated surface functions including remarkable wetting functions such as the directional collection of water droplets and superhydrophobic surfaces simultaneously with unique optical properties will also be presented.
