The interest in highly water-repellent surfaces of SiO2-coated SiC nanowires has grown in recent years
due to the desire for self-cleaning and anticorrosive surfaces. It is imperative that a simple chemical treatment
with fluoroalkylsilane (FAS, CF3(CF2)7CH2CH2Si(OC2H5)3) in ethanol solution at room temperature
resulted in super-hydrophobic surfaces of SiO2-coated SiC nanowires. The static water contact angle of
SiO2-coated SiC nanowires surfaces was changed from 0 to 153 and the morphology, microstructure
and crystal phase of the products were almost no transformation before and after super-hydrophobic
treatment. Moreover, a mechanism was expounded reasonably, which could elucidate the reasons for
their super-hydrophobic behavior. It is important that the super-hydrophobic surfaces of SiO2-coated
SiC nanowires possessed ultraviolet-durable (UV-durable) super-hydrophobicity
