SEM images of as-prepared polymer microstructures after SCTR.
(a) Large-area polymer microstructures. (b–d) SEM images of polymer arrays exhibiting a range of geometries on the silicon substrates. Dark and bright areas correspond to the polymer film and the bare silicon wafer, respectively. (e) SEM images of polymer nanoarrays. (f) Free-standing polymer thin film with ultrafine structures. Scale bars: (a) 1 mm, (b–d) 10 μm, (e) 500 nm, (f) 10 μm.
