摘要
The pattern complexity and functional value of wrinkled structures can be substantially increased by fabricating the wrinkles on pre-patterned quasi-planar substrates instead of flat substrates. This disclosure presents the methods for fabricating pre-patterned polymeric surfaces that can be subsequently used as the substrates during manufacture of complex wrinkled structures. Pre-patterned substrates are generated by imprinting the pre-patterns onto the substrates during the curing process. Suitability for post-curing use in fabrication of wrinkles is ensured by (i) delayed imprinting that occurs close to but before the gelation point and (ii) gradual alignment of pre-patterns to the direction of stretch that is applied later during manufacture of wrinkled structures.
