In this paper, we report a method to fabricate a series of surfaces with large-area ordered binary arrays by controllable dewetting. The binary structure arrays consist of an ordered-stripe array and droplet-row array. In order to expand the system, polystyrene (PS) and poly(methyl methacrylate) (PMMA) are introduced in this experiment for investigation in detail. Through adjustment of the polymer solution concentration and the modified underlying pattern on substrate, the surface topographies can be controlled simply. Accordingly, three types of topographies with ordered binary arrays have been obtained by thermal annealing. These unique surfaces mimic the natural rice leaf structurally, which also displays anisotropic wettability for water droplet as natural surfaces. This method points out a new way for the manufacture of functional surfaces.
本文通过可控的去湿方法，报道了一种制造大面积有序二元数组表面的方法。二元结构数组由有序条纹阵列和液滴列阵组成。为了扩展该体系，本实验中引入了聚苯乙烯（PS）和聚甲基丙烯酸甲酯（PMMA）进行了详细研究。通过调整聚合物溶液浓度和基底上的改性图案，可以简单地控制表面形貌。因此，通过热退火得到了具有有序二元数组的三种类型的表面形貌。这些独特的表面模仿了天然稻叶的结构，并且对水滴表现出了类似于天然表面的各向异性润湿性。这种方法为功能表面的制造指出了一条新途径。
