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.
, Karen K. Gleason, Mary C. Boyce, and co‐workers demonstrate a deterministic method to obtain orderly herringbone patterns through buckling of a stiff thin film deposited by chemical vapor deposition on a compliant substrate. Controlling the stretching and releasing of the sample enables tuning the features of the wrinkled surface, obtaining for the first time jog angles lower than 90°.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
