Fabrication of Elastomer Films with Nano-micro Hierarchical Wrinkled Structure

Abstract

Instabilities are commonly manifested in our daily lives, such as in water jets breaking into isolated drops, wave patterns at the sea surface, sand dunes, cloud waves, ruptures of paint from a wall, and wrinkles on human skin. Previously, we have fabricated hierarchical concentric wrinkled-structures by 3D-stretching method combining UVO and plasma treatments. The hierarchical structure has been achieved via structural transfer. However, the fabrication of hierarchical structures requires a complicated transcription process. In this study, we examined the fabrication of hierarchical wrinkled-structures by 3D-stretching method continuous plasma and UVO treatment.
