Abstract

The hydrophobic effects of Al₂O₃ coatings on glass slides are investigated in this work by comparing dip and spray procedures using three distinct solvents: acetone, polyvinyl alcohol (PVA), and ethanol. Using both dip and spray techniques, the experimental design systematically applies Al₂O₃ coatings on glass slides. Then, the effect of the chosen solvents on hydrophobicity is investigated. Delineating the complex interaction between coating processes and solvent options requires careful analysis of each solvent and regulated application. Measuring the hydrophobicity of coated glass surfaces, which includes the contact angle, allows for quantitative insights into their water-repellent characteristics. Coating efficiency, homogeneity, and the consequent hydrophobic properties are all part of the comparison examination. The study’s findings assist in choosing the best methods for customizing hydrophobic characteristics on glass surfaces for various uses and add to our knowledge of surface modification procedures in general.
