This
paper concentrates on the development of glasses with self-cleaning surfaces
exhibiting high water contact angles. In this study, we prepared
super-hydrophobic nano-ceramic coated glass based on titania &silica
using simple sol-gel & dip coating methods and studied the best composition
of the coatings by altering ratios of titanium tetraisopropoxide
(TTIP)/tetraethyl orthosilicate (TEOS)with
different homogenizing agents.We
characterized the coatings by surface roughness measurement, percentage of
optical transmission, static contact angle, near-infrared (NIR) transmission,
and diffuse reflectance. The fabrication of coatings on glass substrates played
an important role in increasing the water contact angle of about 95° and
visible & NIR transmission of about 90%. We compared our modified glass
substrate with commercial low emissivity (Low E) glass using X-ray diffraction
(XRD) analysis, which showed pure amorphous surfaceclaiming
excellent wettability and thus the prepared glass substrate could have a
variety of applications in different fields.
