A simple method for fabricating high-aspect-ratio, hierarchical, and dynamically tunable surface patterns is invented by harnessing localized-ridge instabilities in gold nanofilms coated on elastomer substrates (a); a theoretical model to calculate the critical parameters (e.g., wavelength and amplitude) for designing the new patterns is developed (b); and novel applications of the patterns as super-hydrophobic coatings (c) and biomimetic cell-culture substrates (d) capable of on-demand tunability are demonstrated.
通过利用涂覆在弹性体基板上的金纳米薄膜中的局部脊不稳定性，发明了一种制造高纵横比、分层且可动态调谐的表面图案的简单方法（a）；开发了一种理论模型来计算设计新图案的关键参数（例如波长和振幅）（b）；并展示了这些图案作为具有按需可调性的超疏水涂层（c）和仿生细胞培养基板（d）的新应用。
