TLDR
The origins of water-repellent surfaces are discussed, examining how size and shape of surface features are used to control surface characteristics, in particular how techniques have progressed to form multi-scaled roughness to mimic the lotus leaf effect.Abstract:
Research into extreme water-repellent surfaces began many decades ago, although it was only relatively recently that the term superhydrophobicity appeared in literature Here we review the work on the preparation of superhydrophobic surfaces, with focus on the different techniques used and how they have developed over the years, with particular focus on the last two years We discuss the origins of water-repellent surfaces, examining how size and shape of surface features are used to control surface characteristics, in particular how techniques have progressed to form multi-scaled roughness to mimic the lotus leaf effect There are notable differences in the terminology used to describe the varying properties of water-repellent surfaces, so we suggest some key definitionsread more

TL;DR: In this paper, the photogeneration of a highly amphiphilic (both hydrophilic and oleophilic) titanium dioxide surface was reported, and the unique character of this surface was ascribed to the microstructured composition of hydrophilicity of the phases, produced by ultraviolet irradiation.
