The generation of structural color from wrinkled polydimethylsiloxane (PDMS) surfaces, fabricated by plasma exposure, subjected to uni- and multi-axial, sequential strain fields is examined. approach based on the well-known, mechanically-induced, buckling instability a supported bilayer, whereby top glassy “skin” formed oxidation. Surface periodicities 200 nm ≲ d 3 μm, encompassing visible spec...
