This talk will describe a memory-based, sequential wrinkling process that can transform flat thermoplastic sheets into multi-scale, three-dimensional hierarchical textures. Multiple cycles of plasma-mediated polymer skin growth followed by directional strain relief of the substrate can produce hierarchical architectures with independent control over wrinkle wavelength and wrinkle orientation. We will discuss how this bottom-up sequential wrinkling process with soft skin layers can produce conformable deformable two-dimensional electronic materials with new structural properties for diverse applications.
