Topography-dependent tuning of water wettability was achieved on a stainless steel surface textured by nanosecond-laser pulses at different laser fluences, with the minimal contribution of the surface chemical modification. Such differently-wet neighboring surface spots were demonstrated to drive an autonomous directional water flow. A series of elementary microfluidic devices based on the spatial wetting gradients were designed and tested as building blocks of "green", energy-saving autonomous microfluidic circuits.
通过纳秒激光脉冲在不同激光能量密度下对不锈钢表面进行纹理化处理，实现了与表面形貌相关的水润湿性调节，且表面化学改性的贡献最小。已证明这种具有不同润湿性的相邻表面斑点可驱动自主定向水流。基于空间润湿性梯度设计并测试了一系列基本微流控装置，作为“绿色”节能自主微流控电路的构建模块。
