<p>There have been a lot of artificial superhydrophobic surfaces, however, those are difficult to use in daily purposes because of their brittle, stiff and breakable properties. We have been reported fabrication of superhydrophobic microstructured vulcanized rubber surfaces by using silicon microstructures as mold during their vulcanization process. Furthermore, the arrangement of microstructures could be repeatedly transformed from a hexagonal to linear patterns by elongations and superhydrophobicity was kept during elongation process. In this report, we prepared other type of superhydrophobic microstructured vulcanized rubber surfaces, which can be changed surface wettability by stretching. The superhydrophobic microstructured vulcanized rubber surfaces were prepared by using a silicon microstructures as mold. After observation of surface structures and wettability by laser microscopy and water contact angle analyzer, we took high-speed photography of water droplets felled to the rubber surfaces with different elongation rates, and theoretically discussed the differences of water behaviors.</p>
