SEM images of the wrinkled PDMS stamps and the polymer patterns via introducing these wrinkled stamps into SCTR.
(a) Metal-coated PDMS stamp with wrinkle patterns. (b) The corresponding polymer nanostructures produced using the PDMS stamp with periodic wrinkles on the surface shown in Figure 3a. (c) The polymer nanostructures after SCTR through the using of PDMS stamp with small enough features and wrinkles on the surface at the same time. Scale bar: 5 μm.
