Abstract Scope |
A controlled wrinkled structure is a simple and effective approach of materials to achieve unique properties, and has been widely used in making material flexible. In this study, we reported a substrate prestrain method to fabricate wrinkled structure on Zr52Ti34Nb14 multiple-basis-element (MBE) alloys films as biocompatible materials. With varied film thicknesses and prestrains applied on the substrate, the amplitude and wavelength of wrinkled structures can be precisely controlled, ranging from micrometers to nanometers. Moreover, due to the flexibility of wrinkled structures, the pattern of the wrinkled structure could be adjusted by simply releasing and further stretching the substrate, which finally leads a dynamically-tunable transmittance and wetting behavior. This result not only enables a Zr52Ti34Nb14 MBE alloys film as potential flexible material, but also provides a new structural design approach for other MBE alloys systems. |
