Development and Analysis of B2O3-TiO2 Glass Coatings for Advanced Functional Applications
Abstract
The novelty of this study, compared to our previous sol-gel coating works, lies in the use of solar panel glass substrates and the comprehensive characterization carried out, including mineralogical, morphological, thermal, and mechanical analyses. The first step in the process is to prepare a sol, which is a colloidal solution consisting of solid particles uniformly dispersed within a liquid medium. Sols utilized within the present study were prepared through hydrolysis and polishing of Titanium and Boron Alkoxides, respectively, within Alcohol. To create the thin film on a glass, each sol was placed onto a glass by the dipping method with the aid of a dip coater, and the coated glasses were allowed to air dry. The characteristics of the surfaces of the processed glasses were determined through cross-sectional testing (XRD), pencil hardness tests, scanning electron microscopy (SEM) and contact angle (CA). The untreated glass surface exhibits a water contact angle of 59.20°, reflecting its inherently hydrophilic character. The contact angle significantly decreases to 10.46°, 17.14°, and 5.34%, respectively. Glasses with TiO2 and B2O3 addressing display increased scratch resistance but decreased CA versus uncoated counterparts.
