The schematic of fabrication process and the structure of DMRWs.
a, The illustration of fabrication. The micro-walls of DMRW are fabricated by PDMS with Fe particles and the basement of DMRW is formed by pure PDMS (both with curing agent). After that, the DMRW is modified with ZnO nano-hairs by enhanced crystal growth method. The surface gets superhydrophobic property after being covered by FAS-17. b-c, SEM images with low magnification in the top view (b) and side view (c) of the DMRWs. Vertical flexible walls are fabricated with width of 200 μm, heights of 500 μm and spacing of 200 μm. d, SEM image with the magnified view of DMRWs, it is covered by ZnO nano-hairs. The diameters of ZnO range from 50 nm to 80 nm. e, the EDS analysis of DMRWs, the mainly chemical constituents are C, O, F, Zn, Fe.
