A novel change method of surface wettability using both micro- and nano-sized geometrical shape is presented in this paper. After the black silicon is formed in reactive ion etching, SU-8 mold is fabricated on top of the black silicon that has nano-sized holes. After the microfabrication of SU-8 photoresist mold, poly-dimethysiloxane (PDMS) is poured into the mold. As a result, the molded PDMS surface has both micro- and nano-sized structures, which is similar to lotus leaf. The diameter of cylindrical pillar micro structures ranges from 50 to 100 μm. The water contact angle of 150° is obtained on the molded PDMS surface with pillars diameter of 50 μm. The superhydrophobic surface made of micro- and nanostructures is straightforwardly formed, increasing water contact angle on the engineered surface.

Superhydrophobic surfaces have been a hot topic during the last decade owing to their great potential in widely application. In this work, we report on a facile and low-cost two-step method to fabricate superhydrophobic surface on steel substrates. The as-obtained surface shows an interesting hierarchical structure composed of microscale flowerlike cluster and nanoscale particles, which is similar to that of a lotus leaf. After further modification with stearic acid, the resultant surface exhibits remarkable superhydrophobic properties. The water contact angle is as high as 155°. Moreover, the superhydrophobic properties are long-term stable.

This paper presents a fabrication technology to create a double roughened PDMS structure for a superhydrophobic surface. The fabricated surface has many application potentials, including on-chip micro liquid processor and water repellent coating. Similar structure can be found in nature on a lotus leaf (Fig. 1.) Due to its superhydrophobic surface, lotus leaf repels water and in the process performs self-cleaning [1]. In this paper, we show the combination of Nanosphere Lithography (NSL), plasma etching, and molding technique to create the micro/nano integrated double structure using PDMS. Also described is the design procedure and experimental results for the double-structured superhydrophobic surface.
