Superhydrophobic coating from self-assembly of nanoparticles Aktanberdi Askerbay Department of Chemistry, School of Science and Technology, Nazarbayev University, Astana, Kazakhstan Email: [email protected] Abstract High transparency is important to the performance of optical equipment and devices, such as windows, lenses, solar panels, and safety goggles. As many of them are exposed to various environmental conditions, there is a growing demand to develop new solutions in the production self-cleaning coating that can prevent microbial growth, fouling, corrosion and icing. One of the best technologies to solve these problems is superhydrophobic coating. This research discusses recent advances in design, synthesis and fabrication of transparent, superhydrophobic surfaces. First, we revisit different models of superhydrophobicity and present the potential challenges in the nanofabrication of transparent superhydrophobic surfaces. We then discuss the general fabrication methods, including the top-down fabrication methods and self-assembly approaches, to create roughness with a size in the sub-visible wavelength with or without posthydrophobilization steps. The study concludes with perspectives on future directions and challenges in manipulation of surface nanoroughness, specifically, using nanoparticles, for both high transparency and superhydrophobicity and their potential applications.
