Assessment of antimicrobial efficacy of leather coating using chitosan modified TiO₂-CuO nanocomposites.

ABSTRACT: This research investigates the microbial inactivation potential of ternary TiO₂-CuO-chitosan nanocomposites (TCC NCs) applied as surface coatings on cowhide leather. Initially, bare TiO₂ nanoparticles (NPs) and binary TiO₂-CuO (TC) NCs, with varying CuO NPs content, were prepared using an in situ sol-gel method. These binary TC NCs were then modified with chitosan at varying weight percentages (2%, 4%, 6%, and 8%). The resulting NCs were analyzed using various spectral tools. XRD analysis revealed the dominance of the anatase form of TiO₂ in both binary and ternary NCs. UV-visible DRS measurements were used to study the optical properties of the NCs and compare these to those of individual components. Microscopic analysis indicated the for
