In this paper, a grooved mushroom structured surface, with superoleophobicity and anisotropic flow of hexadecane with a low surface tension is reported. The grooved mushroom structure was fabricated using a simple and cost-effective wet etching process on Si wafer. The wetting properties of the fabr...
