Study of the Hydrophobic Properties of the Surface of an Enamel Material

Abstract:

The hydrophobic properties of the surface of an enamel material are reported in this paper. By using a sol-gel method and with tetraethoxysilane as the precursor which is combined with dimethyldichlorosilane (DDS), the films composed of DDS-SiO₂ nanoparticle composite materials were prepared on an enamel surface, with the droplet’s contact angle increased, and the properties of the enamel surface changed from hydrophilic to hydrophobic. The properties were tested, the hydrophobic mechanism was studied based on the investigation of the microstructure and the crystal structures of the film by scanning electron microscopy, X-ray diffraction and infrared spectrum analysis.
