Title: An anti-UV superhydrophobic material with photocatalysis, self-cleaning, self-healing and oil/water separation functions

Abstract: In this work, a superhydrophobic material was successfully prepared with a water contact angle of about 155.5° and a rolling-off angle of about 6.8°, which showed superior UV resistance (365 nm, 5.0 ± 0.6 mW cm−2) for an illumination period of 30 h. The degradation of organic dyes, such as Nile red, methyl blue and orange, could be also achieved with our prepared surface. Anti-UV water-repellency was combined with photocatalysis to realize a self-cleaning surface for both dirt removal and organic degradation. Moreover, the reversible changes with superhydrophobicity and superhydrophilicity were induced by the self-healing property on such a surface, contributing to heavy and light oils/water separation. Because of ultra-long UV-resistance, photocatalysis, self-cleaning, self-healing and oil/water separation functions, our reported surface has potential for application in a variety of fields.
