Figure 21From: Hierarchical micro/nano structures for super-hydrophobic surfaces and super-lyophobic surface against liquid metalContact angle of mercury droplet. Contact between droplets of mercury resting on the surfaces (a, b, c) and being detached from them (d, e, f). The columns correspond to (a, d) the polished singe crystal, (b, e) the micro-crystalline diamond and (c, f) the oxidized sample.Back to article page
