Influence of Structural Characteristics on the Wettability of Al₂O₃-Reinforced Epoxy Coatings

Aluminum oxide (Al2O3) is a ubiquitous material with a wide range of applications due to its exceptional properties. This paper explores the relationship between the structural characteristics of Al2O3 and its surface wettability, as measured by contact angle. Using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, the crystalline structure and chemical properties of the epoxy-Al2O3 samples were characterized. Contact angle measurements were performed to evaluate the wettability of epoxy-Al2O3 surfaces. The results reveal a strong correlation between the structural characteristics and the hydrophobic nature of the coating surfaces. These findings have significant implications for the use of epoxy-Al2O3 coatings in applications requiring specific wettability properties.
