Fig. 7

a Schematic illustration of the soft lithography process to pattern SPI film. b Optical image of the micro-patterned film. Scale bar represents 5 mm. c SEM image of the side view (top) and top view (bottom) of patterned micropillars. Scale bars represent 25 μm (top) and 100 μm (bottom). d Optical images of a water droplet on the film without (top) and with (bottom) micropillars. Scale bars represent 1 mm. e Water contact angles of the films, showing an increase of hydrophobicity in the patterned film. The indicated error bars are the s.d. of the average of three independent measurements. f, g Optical image of non-patterned (f) and nano-patterned photonic film (g). h, i SEM image of the nano-patterned film. Scale bars represent 20 μm (h) and 2 μm (i).
