Abstract
Urushiol-based coatings have attracted considerable interest as sustainable coating materials owing to their high gloss, flexibility, and environmental compatibility. However, their relatively low resistance to scratching and abrasion limits broader industrial applications. In this study, silica (SiO2) nanoparticles were surface-modified through in situ treatment, APTES functionalization, and VTES functionalization to investigate the influence of surface chemistry on nanoparticle dispersion and coating durability. The modified nanoparticles were incorporated into urushiol matrices at various loadings to fabricate hybrid coatings. Differences in nanoparticle dispersion and interfacial interactions arising from the surface functional groups were systematically examined using microscopic and spectroscopic analyses. The scratch and abrasion resistance of the resulting coatings were evaluated and correlated with nanoparticle dispersion behavior and interfacial characteristics. This study aims to clarify the relationship between silica surface functionality, microstructural evolution, and mechanical durability, providing design guidelines for high-performance bio-based coating systems.
