摘      要：Cinnamaldehyde-tannic acid-zinc acetate nanoparticles (CTZA NPs) assembled from edible medicinal plant extracts were successfully incorporated into chitosan films. FTIR spectroscopy analysis indicated that there were strong electrostatic and hydrogen bond interactions between the chitosan and CTZA NPs in the film matrix, which led to an increase in the tensile strength of the films by around 525%. Incorporation of 0.6% or 0.8% CTZA NPs led to films that could undergo appreciable stretching in water without breaking which was attributed to the high hydrophobicity of the nanoparticles. Furthermore, the incorporation of the CTZA NPs enhanced the UV adsorption, antibacterial, and antioxidant properties of the films, while reducing their water vapor permeability. Moreover, it was possible to print inks onto the films because the presence of the hydrophobic CTZA NPs facilitated the deposition of carbon powder onto their surfaces. The films produced in this study may therefore be useful for commercial applications. © 2023, The Authors. All rights reserved.
