Anti-UV superhydrophobic material with photocatalysis, self-cleaning, self-healing and oil/water separation
In this work, a superhydrophobic material was successfully prepared with the water contact angle of about 155.5° and rolling-off angle of about 6.8°, which showed superior UV resistance (5.0 ± 0.6 mW/cm2) for 30 hr illumination. And, degradation of organic dyes, such as, Nile red, methyl blue and orange, could be also achieved by our surface. Anti-UV water-repellency was combined with photocatalysis to realize a self-cleaning surface both for dirt removals and organic degradations. Moreover, the reversible changes with superhydrophobicity and superhydrophilicity were induced by self-healable property on such surface, contributing to heavy and light oils/water separations. Because of ultra-long UV-resistance, photocatalysis, self-cleaning, self-healing and oil/water separation, our reported surface is prospected for the application in a variety of fields.
