“…And the surface was secondarily modified by stearic acid or 1,1,2,2tetrahydroperfluorodecyltrimethoxysilane (FAS) (Figure 8A). Gao et al [124] employed multiarc ion plating to prepare ultrathin titanium-based hard coatings on the substrate, which were then modified by perfluorodecyltriethoxysilane (PFDS). In both cases, multiscale nano/micro-structured superhydrophobic surfaces with a water contact angle of 150 • could be achieved (Figure 8B).…”

Recent Advances in Fabrication of Durable, Transparent, and Superhydrophobic Surfaces

“…Gao et al [ 53 ] reported a robust, transparent, and superhydrophobic fluorinated TiO 2 nanotube (F-TNTs)/TiN coating, fabricated through surface structure tuning of TiN ( Figure 4 a). A composite structure was created by depositing an ultra-thin TiN coating using multi-arc ion plating, followed by anodic oxidation to form the embedded TiO 2 nanotube arrays.…”

A Fluorine-Free Superhydrophobic Micro–Nano Structured SiO2/TiN Coating for Anti-icing and Photothermal Deicing

“…A superhydrophobic surface offers an effective way to delay the icing time. − This is based on the presence of an air layer within the surface textures, which can greatly reduce the contact areas between water droplets and solid substrate. − The introduction of photothermal materials into superhydrophobic coating can effectively convert solar energy into thermal energy and promote the ice melting at the interface and then the removal of unmelted ice by gravity or superhydrophobicity. − Liu and co-workers constructed an all-water-based superhydrophobic coating by using carbon nanotubes, polydopamine, and Ag particles as photothermal materials and then mixing them in fluorine-containing polyacrylic emulsion . Under the irradiation of a xenon lamp, the melting time of the ice cubes on the coating surface was reduced by 982 s. Apart from the commonly used carbon-based materials and black metal oxides, − low-cost titanium nitride (TiN) nanoparticles have been proven recently to possess a plasmonic effect that can be used for photothermal conversion. ,− Wang’s groups have fabricated a flexible photothermal coating by embedding TiN nanoparticles in polydimethylsiloxane solution . It can be heated to 130 °C within 90 s under near-infrared (NIR) laser irradiation.…”
