Natural and biomimetic artificial surfaces for superhydrophobicity, self-cleaning, low adhesion, and drag reduction (2011, background): “However, it has been stated that the wax on the Lotus leaf surface, by itself, is weakly hydrophilic [194].”
Recent advances in TiO2-functionalized textile surfaces (2021, background): “While the contact angle of water on hydrophobic surfaces is greater than 90, superhydrophobic surfaces with low adhesion are characterised by a water contact angle of more than 150, minimal contact angle hysteresis and a water roll-off (sliding) angle of less than 10 [215].”
Micro-, nano- and hierarchical structures for superhydrophobicity, self-cleaning and low adhesion (2009, background): “However, it has been stated that the wax on the lotus leaf surface, by itself, is weakly hydrophilic (Tuteja et al. 2008).”
Vapor chambers with jumping-drop liquid return from superhydrophobic condensers (2013, methodology): “by adopting superoleophobic condensers via surface patterning (see for example [27]) or using working fluids of large surface tension (mercury condensate can jump upon coalescence on a flat surface [28]).”
