Multifunctional Superhydrophobic Nanocomposite Surface
Published in Sam Zhang, Jyh-Ming Ting, Wan-Yu Wu, Functional Thin Films Technology, 2021
In addition to anti-icing, condensation, superamphiphobicity, oil–water separation, anti-corrosion and wettability conversion, functional superhydrophobic surfaces also have many other unique properties, such as adhesion, fog collection, transparency, antibacterial properties, and so on.

Ideally, a collector should allow tiny fog droplets to reappear on a free surface and drain with gravitational force without clogging (Azad et al., 2015). Superhydrophobicity offers low surface energy to incoming droplets on FCE and forces them to slide down rapidly. Organism silanes are capable of creating hydrophobic surfaces through silane surface allocation, organic substitutions, unreacted silane groups, as well as surface coverage. The organic substitution must be non-polar to produce superhydrophobicity. Hydrocarbon molecules can be shifted from aqueous state to uniform hydrocarbon state, which may account for superhydrophobicity of organic substitution (Azeem et al., 2022). Fog collection rate depends on many factors; e.g. collector size, collector design, efficiency, liquid water content in the air, and incoming wind speed. The typical liquid water content was recorded at 0.1–0.5 gm−3 (Roth-Nebelsick et al., 2012). Herein, we are only discussing the collector design and surface modification.

Due to the seriousness of this issue, the researchers have been looking for other resources for drinking water supply in the past two decades (Jiang et al., 2019; Jiang et al., 2019). Meanwhile, fog has attracted the attention of the scholars as a favorable resource for drinking water supply so that several projects have been devoted to it in over 17 countries of the world, including Peru, Oman, Yemen, Nepal, etc. and the United Nations reported that fog collection is an appropriate and cheap technology for drinking water supply, agricultural use, livestock use, and also to revive the forests in highlands (Shi et al., 2018; Park et al., 2013). In the regions where there is insufficient rainfall, fog collection can be a profitable way to supply the necessary water (Xing et al., 2019).
