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

This research investigates the microbial inactivation potential of ternary TiO-CuO-chitosan nanocomposites (TCC NCs) applied as surface coatings on cowhide leather. Initially, bare TiO nanoparticles (NPs) and binary TiO-CuO (TC) NCs, with varying CuO NPs content, were prepared using an sol-gel method. These binary TC NCs were then modified with chitosan at varying weight percentages (2%, 4%, 6%, and 8%).
