Abstract

The aim of this study was to investigate the physicochemical properties of chitosan (CS) based composite films with the incorporation of hemicelluloses (HC). Films were obtained via direct immersion method and characterized in terms of structural and morphological properties by FT-IR, XRD, XPS, SEM and EDS. By combining with the increased HC loading efficiency (L) and swelling property (S) of films with the increased HC content to 5%, this study proved the increased hydrogen bond interactions between CS and HC. Films with the tensile strength of 32.81 ± 4.97 MPa and elongation at break of 39.63 ± 4.67% were obtained with 3% HC and 20% glycerol (GC). The water vapor permeability (WVP) of films developed with the increased HC and GC contents, while the oxygen permeability (OP) decreased. Moreover, antibacterial testing indicated that all films exhibited the increased growth inhibition against E. coli and S. aureus as increasing TiO₂ content.
