Hydrophobic inorganic films were obtained by direct deposition of copper or silicon onto natural lotus leaves by ion beam sputtering deposition technique. Scanning electron microscopy observations showed a lotus-leaf-like surface structure of the deposited inorganic films. Hydrophobic nature of the inorganic films on lotus leaves had been improved compared to the inorganic films deposited on flat silicon substrates. Water contact angles measured on the lotus-leaf-like copper and silicon films…

Investigation on hydrophobicity of lotus leaf: Experiment and theory
TLDR
The investigation results showed that the hydrophobicity of the front surfaces was dominated by the entrapped gas under the drop and the absolute stable position of the contact line while the back surfaces were dominated by metastable positions of thecontact line, resulting in the ultrahydophobicity on the frontsurface and large contact angle hysteresis on the back surface.

TLDR
It is shown that the hydrophilic stamps can be used for the repetitive printing of at least 10 consecutive patterns, which preserve their etch resistance, and this in rather sharp contrast to conventional and oxygen plasma-treated PDMS stamps.
