Preparation, characterization and application of chitosan/thyme essential oil composite film.

ABSTRACT: In order to prepare a chitosan-based antibacterial film with excellent mechanical properties and study its properties, the tape casting method was used to prepare the composite film from chitosan, glycerin and thyme essential oil. Through single factor test and response surface optimization test, the tensile strength and elongation at break were used as response indicators to prepare the composite film with better mechanical properties, and the physical properties, water vapor permeability, solubility and bacteriostasis of the composite film were measured, and the characterization of the microstructure of the composite films. The results showed that the optimized composite film ratio was 1.5% chitosan, 0.5% glycerol, 0.5% thyme essential oil, 18.69 MPa tensile strength, 19.01% elongation a
