Abstract
Environmentally friendly water-resistant and antimicrobial packaging materials have been developed. Paper sheets were coated with chitosan and stearic anhydride, and then were loaded with silver nanoparticles. A simple dipping method was performed to coat the paper sheets with chitosan. Stearic anhydride was used for surface hydrophobic modification assisted by microwave heating. The treated paper sheets were then characterized by FTIR, SEM and EDAX. Mechanical properties, air permeability, Cobb test, contact angle and antimicrobial tests against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans were also investigated.
