作者报道了在聚二甲基硅氧烷薄膜上各种亚微米褶皱图案的形成及其从一维波纹到二维人字形结构的转变。使用机械力，他们可以分别控制施加在两个平面方向上的基板上的应变的数量和时间（同时或顺序），这似乎是实时操纵图案形成的关键。他们展示了从平面到一维波纹，到分岔波纹，到波纹/人字形混合特征，以及高度有序的基于之字形的二维人字形结构的良好控制形成的可逆转变。(c) 2007年美国物理学会。
The authors report the formation of various submicron wrinkle patterns and their transition from one-dimensional (1D) ripples to two-dimensional (2D) herringbone structures on poly(dimethylsiloxane) films. Using mechanical force they can separately control the amount and timing of strain applied to the substrate on both planar directions (either simultaneously or sequentially), which appears to be critical to maneuver the pattern formation in real time. They demonstrate reversible transitions from flat to 1D ripple, to ripple with bifurcation, to ripple/herringbone mixed features, and to well-controlled formation of a highly ordered zigzag-based 2D herringbone structures.
