Many studies have examined the formation of surfaces with mixed patterns of micro-and nano-sized lotus leaves that have hydrophobic properties. In this study, micro-and nano-shapes such as lotus leaves were fabricated on a metal mold surface using laser ablation and ripple formation. A microstructure on the mold surface was replicated onto poly(dimethylsiloxane) (PDMS) using the polymer casting method to manufacture low-cost hydrophobic surfaces. A PDMS surface with micro-and nano-structures that were the inverse image of a lotus leaf showed hydrophobic characteristics (water contact angle: 157 degrees). From these results, we deduced that portions of the microstructures were wet and that air gaps existed between the microstructures and the water drops. In this paper we suggest the possibility of the mass production of hydrophobic plastic surfaces and the development of a methodology for the hydrophobic texturing of various polymer surfaces, using the polymer casting method with laser-processed molds.
