Femtosecond laser microfabrication is emerging as a hot tool for controlling the wettability of solid surfaces. This paper introduces four typical aspects of femtosecond laser induced special wettability: superhydrophobicity, underwater superoleophobicity, anisotropic wettability, and smart wettability. The static properties are characterized by the contact angle measurement, while the dynamic features are investigated by the sliding behavior of a liquid droplet. Using different materials and machining methods results in different rough microstructures, patterns, and even chemistry on the solid substrates. So, various beautiful wettabilities can be realized because wettability is mainly dependent on the surface topography and chemical composition. The distinctions of the underlying formation mechanism of these wettabilities are also described in detail.
飞秒激光微加工正成为一种用于控制固体表面润湿性的热门工具。本文介绍了飞秒激光诱导特殊润湿性的四个典型方面：超疏水性、水下超疏油性、各向异性润湿性和智能润湿性。静态特性通过接触角测量来表征，而动态特性则通过液滴的滑动行为来研究。使用不同的材料和加工方法会在固体基底上产生不同的粗糙微观结构、图案甚至化学性质。因此，由于润湿性主要取决于表面形貌和化学成分，可以实现各种漂亮的润湿性。本文还详细描述了这些润湿性潜在形成机制的差异。
