Abstract:

SiOznanostructure films are used as diffusion barrier coating. Due to low cost and easy to use, sol-gel method is frequently used to apply SiO2 films. SiO2 nanostructure film was prepared on automotive glass by sol-gel method applying dip-coating technique in this study. Tetraethyl orthosilicate (TEOS) was used as the precursor material, concentrated HCl as catalyst and organic material as solvent. The coating was applied by dipping the automotive glass substrate on SiO, sol and withdrawing at speed of 60 mm/min. Optical properties were investigated by UV-Vis spectrophotometer. Field-Emission Scanning Electron Microscopy (FE-SEM) observations were performed to characterize the microstructure of the coating. The results show that applying SiO2 nanostructure film on automotive glass substrate increases light transmittance more than 2%. SEM results showthat surface morphology of SiO2 nanostructure film have condensed, uniform and without porous structure.
