固体表面润湿性的四个典型方面，即超疏水性、可控水附着性、各向异性滑动和各向异性润湿，在理论研究和实际应用中引起了极大的兴趣。然而，如何用一种简单有效的方法来实现所有这些性质仍然是一个巨大的挑战。在这里，我们提出了一种利用飞秒激光简单而高效地实现周期性线纹聚二甲基硅氧烷(PDMS)表面的方法。通过调整相邻微槽的周期(D)或平均距离，所制备的表面可以表现出超疏水、可控的水附着性、各向异性滑动和各向异性润湿。我们相信，这些多功能表面在新型微流控器件、微滴操纵、液体微滴定向转移和芯片实验室方面有着巨大的潜在应用。
The superhydrophobicity, controllable water adhesion, anisotropic sliding, and anisotropic wetting, which are four typical aspects of the wettability of solid surfaces, have attracted much interest in fundamental research and practical applications. However, how to use a simple and effective method to realize all those properties is still a huge challenge. Here, we present a method to realize periodic line-patterned polydimethylsiloxane (PDMS) surfaces by a femtosecond laser simply and efficiently. By adjusting the period (D) or average distance of adjacent microgrooves, the as-prepared surfaces can exhibit superhydrophobicity, controllable water adhesion, anisotropic sliding, and anisotropic wetting. We believe that these multifunctional surfaces have enormous potential applications in novel microfluidic devices, microdroplet manipulation, liquid microdroplet directional transfer, and lab-on-chips.
