Description 248-256
In this research, nanocomposite (NC) films comprising chitosan with 20% weight glycerol have been reinforced using
three different types of nanoparticles—TiO2, Ag, and Fe2O3 at concentrations of 1%, 3%, and 5% by weight, respectively, in
various combinations. The characteristics of these NC films have been compared with those of both pure chitosan and
chitosan containing 20% weight glycerol. The incorporation of nanoparticles significantly altered the mechanical and barrier
properties of the chitosan films. Notably, the tensile strength have experienced an increase ranging from 22% to 84%, while
the water vapour transmission rate (WVTR) decreased by 16% to 56%, depending on the nanoparticle dispersion under
consideration. The chitosan 3% Fe2O3 NC film have exhibited the lowest WVTR value and the highest tensile strength when
compared to the chitosan/3% Ag NC film. The minimum WVTR value has been observed in the chitosan/3% Fe2O3 NC film
compared to the chitosan film. The materials and their composites have been analyzed using wide-angle x-ray diffraction
patterns to calculate microcrystalline characteristics. To explore the microstructural behaviour of the chitosan and TiO2, Ag,
Fe2O3 composites and establish a connection with physical characteristics such as tensile strength and percentage elongation,
an exponential asymmetric column length distribution function approach has been employed.
