Facile and cost-effective fabrication of patternable superhydrophobic surfaces via salt dissolution assisted etching
Abstract(#br)Superhydrophobic surfaces with extremely low wettability have attracted attention globally along with their remarkable characteristics such as anti-icing, anti-sticking, and self-cleaning. In this study, a facile and cost-effective approach of fabricating patternable superhydrophobic surfaces, which can be applied on various substrates (including large area and 3D curvilinear substrates), is proposed with a salt-dissolution-assisted etching process. This novel proposal is environmentally benign (entirely water-based and fluorine-free process).
