Superhydrophobic surfaces in nature have often been studied either from the fundamental point of view or for practical applications because they have potential usages in various industrial areas. Many studies have reported on how to realize the superhydrophobic surfaces based on rather cumbersome methods, however, those preparation methods are typically too complicated for full commercialization. Herein, we report a simple and novel fabrication strategy to produce transparent and superhydrophobic surfaces over large area based on hydrophobic SiO2 nanoparticles combined with spray coating. The superhydrophobic surfaces were obtained by the one-coat spray deposition of fast curing epoxy-thiol binders under ambient condition. This simple process resulted in superhydrophobic surfaces with hierarchical morphologies with an optimal binder-particle ratio to guarantee the transparency of coatings. The spray coating process was universally applied to a variety of substrates. |
