Abstract
Ordered herringbone patterns with deterministic long and short wavelengths are created using a sequential wrinkling strategy (SWS). Patterns with a prescribed zig-zag turning angle less than 90° are obtained upon sequential wrinkling of non-equi-biaxial prestrain for the first time. SWS provides a new method for measuring thin-film mechanical properties simply through the wrinkling metrology without measurement of film thickness.
摘要
采用顺序起皱策略（SWS）可生成具有确定长波和短波的有序人字形图案。首次通过对非等双轴预拉伸进行顺序起皱，获得了预定的锯齿形转角小于 90°的图案。SWS 提供了一种新的方法，通过起皱计量学即可测量薄膜的机械性能，而无需测量薄膜厚度。
