A study was conducted to fabricate a microstructure on a poly(dimethylsiloxane) (PDMS) surface using a porous silicon wafer as a mold. The microstructured PDMS surfaces were deposited with gold and imaged using scanning electron microscopy (SEM). The average height and width of the microrods measured using scanning electron microscopy imaging were 10 and 8 μm. The results show that the water contact angle was 103° on the flat surface and 131° on the microstructured surface, resulting in the microstructure increased hydrophobicity.
