Wettability, optical property of a superhydrophobic YAG film

Abstract A flame-like superhydrophobic yttrium aluminum garnet surface was obtained by a simple approach under ambient conditions. The influences of the concentration of curing agent and paraffin wax in course of the experiment were investigated. The as-prepared film shows superhydrophobicity which has a water contact angle of 158 ± 1.0°, and sliding angle of 4 ± 1.0°. Moreover, the water contact angle of the rough surface remained higher than 150°, after exposure for 10 days. Transmission electronic microscope, scanning electronic microscope, fluorescence spectrometer and atomic force microscope were also used to characterize the samples.
