A hydrophilic-hydrophobic hybrid surface with a vein-like pattern was prepared on a copper substrate using 3D printing technology and laser scanning technology. Under the action of the Laplace pressure gradient and wettability gradient, the superhydrophilic (SHL) vein-like pattern on the superhydrophobic (SHB) surface aided the directional transport of water droplets. The presented scheme combined with the wettability and surface pattern could achieve a water-collection efficiency of 4258.59 mg cm h.
利用3D打印技术和激光扫描技术在铜基底上制备了具有静脉状图案的亲水-疏水混合表面。在拉普拉斯压力梯度和润湿性梯度的作用下，超疏水（SHB）表面上的超亲水（SHL）静脉状图案有助于水滴的定向传输。所提出的方案结合润湿性和表面图案可实现4258.59 mg cm h的集水效率。
