The surface of your PDMS film was rinsed successively with fresh developer and deionized water just before drying. Ultimately, the displacements applied towards the PDMS sheet have been released in each planar directions simultaneously, which made an array of curved film microstructures. The forming process of film microstructures corresponding towards the fabrication measures is shown in Figure 2b. The two-dimensional (2D) morphology of your curved film microstructures was assessed by utilizing an optical microscope (Olympus STM6-F10-3, Olympus Co., Tokyo, Ja(b) pan), while the 3D morphology on the curved film microstructures was assessed by using a laser scanning confocal microscope (Nikon A1, gold-coated, Nikon, Tokyo, Japan). The 2D cross-sectional view of the curved film microstructures was examined by optical microscope (Nikon SMZ1270, colored film microstructures, Nikon, Tokyo, Japan). The 2D Figure 2.
