We demonstrate the possibility of producing regular, long-range, spatially ordered polymer patterns without requiring the use of physical or chemical templating through the interfacial destabilization of a thin polymer film driven by surface acoustic waves (SAWs). The periodicity and spot size of the pattern are observed to be dependent on a single parameter, that is, the SAW frequency (or wavelength), therefore offering a rapid, simple, yet novel method for self-organized regular spatial polymer pattern formation that is far more tunable than conventional polymer patterning procedures.
我们证明了通过表面声波（SAW）驱动的聚合物薄膜界面失稳，无需使用物理或化学模板就能产生规则、长程、空间有序的聚合物图案的可能性。观察到图案的周期性和光斑尺寸取决于单个参数，即SAW频率（或波长），因此提供了一种快速、简单且新颖的自组织规则空间聚合物图案形成方法，该方法比传统的聚合物图案化程序更具可调性。
