Inspired by the hierarchical structures of self-cleaning lotus leaves and water-collecting beetle shells, biomimicking surfaces have been extensively investigated for potential applications in self-cleaning, water harvesting, energy saving, and heat transfer. This thesis addresses the design and fabrication of superhydrophobic surfaces with hierarchical micro/nano roughness, and the dynamic wetting characterization in drop impact and condensation experiments. Our experimental observations indicate the hierarchical superhydrophobic surfaces possess robust water-repellence properties and can potentially enhance dropwise condensation heat transfer. We developed a modified deep reactive ion etching (DRIE) method that is capable of realizing uni...
