Description
Soda-lime-silica glass is widely utilized in industrial and domestic applications. In certain cases, changes in the surface properties are needed. This study investigates the surface modification of soda-lime-silica glass using tetraethyl orthosilicate (TEOS) dissolved in dry toluene and employing dip-coating method.
The modified surfaces were characterized using a range of analytical techniques and methods: contact angle measurements, ratio-reflectance and 2T2D correlation spectra obtained from the measured specular-reflectance FTIR spectra and isoelectric point to evaluate alterations in surface charge. Additionally, AFM was used to examine surface morphology.
Results indicate successful glass surface modification with TEOS and interesting morphology of the film, leading to a very small increase in the water contact angle. These findings suggest that glass surface modification with TEOS from dry toluene as solvent, covers and shields the glass surface, while retaining the hydrophilicity.
