Natural surfaces exhibit a large topographical variety. a) SEM images of leaves and insect wings utilized in this study. b) Fabrication scheme to imprint natural surface designs onto polystyrene. Once the PDMS mold has been crosslinked, a polystyrene film is placed on top of it, pressed, and heated to transfer the natural surface topography to polystyrene. c) Leaf imprints can be transferred to polystyrene with high fidelity, as seen in the profilometric images of red rose and its imprint counterpart. d) Insect wing imprints can be transferred to polystyrene with high fidelity, as seen in the SEM images of Huechys incarnata and its imprint counterpart.
