Green nanocoating-based chitosan and starch decorated with Egyptian kaolinite doped by ZnONPs for antimicrobial paper coating

Article scientifique 2023 Anglais

Résumé

Abstract The paper coating is an out-layer of the paper that plays an important role in a paper’s properties, functionality and application. The nanocoating is a multifunction layer that supplied the paper with unique features. In this present work, nanocoating formulas were prepared using a green method and component as well. The nanocoating formulas were based on biopolymers (nanostarch and nanochitosan) decorated with Egyptian kaolinite doped with zinc nanoparticles (Ka/ZnONPs) as support for multifunctional uses. The nanocoating formulas were characterized using a physiochemical analysis as well as a topographical study. Additionally, the prepared nanocoating formulas affirmed an excellent antimicrobial activity as a broad-spectrum antimicrobial active agent with excellent activity against all representative microbial communities. Besides, the coated paper's optical, mechanical and physical properties were improved.
