In this study, we developed a novel method to synthesize mechanically/thermally robust self-cleaning surfaces with superior transparency. The atmospheric pressure (AP) plasma technique was utilized to create metal-oxide coatings with hierarchical structures. Due to dense hydroxyl groups covered on the textured surface, the multilayer growth of fluoroalkylsilane was triggered and formed robust thick films. The as-synthesized coatings possessed static contact angle (SCA) of 160 degrees toward water with low sliding contact angle (< 5°) and the SCA of 125 degrees toward hexadecane. Such superior surface properties were well maintained even after sand abrasion or heating up to 325 ℃. This technique was conducted at room temperature and can be applied to various substrates, such as paper, glass, stainless steels, etc. The hierarchically-structured, superhydrophobic/oleophobic, transparent coatings synthesized via facile route contribute remarkable liquid repellency compared to conventional approaches and shed light on the development of novel, scalable, cost-effective and multifunctional surfaces.
