“…Superhydrophobic materials are one class of novel materials with special wettability, which are utilized extensively in many areas of basic and applied research. Recent advances have demonstrated that air layers can be trapped in the liquid–solid interfaces of superhydrophobic materials, which can decrease the contact area between superhydrophobic materials and liquid to show excellent water repellency. − Because of their special wettability, these materials are promising for self-cleaning, , oil/water separation, , corrosion resistance, ,, biological techniques, − and anti-icing. , Among various functional superhydrophobic coatings, luminescent superhydrophobic coatings have generated particular interest and developed rapidly. They have widespread applications in sunlight conversion of agriculture, − anticounterfeiting technologies, , bioimaging , and optoelectronic devices. , Xu et al prepared a fluorinated polypyrene/silica hybrid superhydrophobic film, one-step electrochemical polymerization created rough structures, and strong fluorescence .…”
