Abstract

The structures and UV resistance of Ag/SnO2 nanocomposite materials was observed in this study for coating applications. Horizontal Vapor Phase Growth (HVPG) was used to synthesize the Ag/SnO2 nanocomposite materials. The ratio between Ag and SnO₂ was fixed with stoichiometric mixtures of 0:5, 1:4, 2:3, 3:2, 4:1, and 5:0. Scanning electron microscope–energy-dispersive X-ray spectroscopy (SEM–EDX) was used to evaluate the morphology of the materials. The results were then compared with Density Functional Theory (DFT) analysis. Computational DFT analysis of the SnO₂ (110) and Ag (111) cells have verified nanorods formation of the composite material. Moreover, DFT results of Ag/SnO₂ confirmed the UV blocking properties from their computed electrical bandgap energies of the range from 2.72 to 4.84 eV. The highest UV absorbance of nanocomposite was observed for 1:4 Ag/SnO₂ stoichiometric ratio with 8.09 A. The study shows that the ration of SnO₂ over Ag increases, the absorbance increases as well.
