Self‐Wrinkling of UV‐Cured Polymer Films

Abstract

One-step, highly controlled self-wrinkling of UV-cured polymer films is reported. During UV-curing a top layer of non-polymerized monomers, present due to oxygen inhibition, self-swells and wrinkles the bottom crosslinked film. Wrinkle wavelength and amplitude are controlled by controlling resin film thickness, oxygen partial pressure, and photoinitiator concentration. Patterned wrinkles are fabricated by spatial patterning of oxygen surrounding the curing film. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
