The super-hydrophobic surfaces of SiO2-coated SiC nanowires were obtained by a simple, effective and mild chemical coating approach. Notably, there was almost no change in the morphology, microstructure and crystal phase of SiO2-coated SiC nanowires before and after super-hydrophobic treatment. Moreover, the reason for the SiO2-coated SiC nanowire surfaces exhibiting super-hydrophobic behavior was that FAS molecules were successfully bonded to the product surfaces, on which the hydrophobic groups of the FAS molecules point the outside. In addition, the analysis results reveal that the super-hydrophobic surfaces of SiO2-coated SiC nanowires can exhibit UV-durability. Consequently, it is entirely reasonable for us to believe that the technique can achieve large-scale production of the super-hydrophobic SiO2-coated SiC nanowires in new industrial applications.
