Research of Rough Structure of Superhydrophobic Film
Abstract:
Superhydrophobic film was fabricated mainly by ethyl silicate (TEOS) and ethanol (EtOH) using sol-gel method. SiO2 gel and samples coated with SiO2 sol were calcined at different temperatures, and their morphology and composition were studied using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The results indicate that increasing calcining temperature appropriately improved the bond of nanoparticles of film successfully. Furthermore, there were only amorphous SiO2 and hydroxyl existing in the calcined film which would be benefit for the further modification.
