Description
Summary:In this study, we fabricated a dysprosium cerium oxide-based nanostructure (Dy2Ce2O7) using a rapid and eco-friendly combustion method facilitated by mango extract. Characterization techniques confirmed that the synthesized Dy2Ce2O7 nanostructures exhibited a uniform spherical morphology with a cubic crystal structure. These nanostructures were then integrated into a wheat starch/sage seed gum (WS/SSG) film matrix at varying concentrations (1–4 wt%). FTIR analysis revealed hydrogen bonding between Dy2Ce2O7 and the WS/SSG matrix, while XRD patterns demonstrated effective dispersion of the nanostructures within the matrix. According to FESEM observations, the addition of Dy2Ce2O7 introduced pronounced surface protrusions, yielding a rougher film morphology. Thermal stability testing via TGA indicated that the film residue at 600 °C increased substantially as Dy2Ce2O7 content increased. The inclusion of Dy2Ce2O7 nanostructures also significantly decreased the film's surface hydrophilicity, solubility in water, and water vapor permeability (WVP). UV transmittance testing indicated notable reductions in UVA, UVB, and UVC penetration by 95 %, 97 %, and 99 %, respectively, in the WS/SSG/Dy4 film compared to the control WS film. These findings highlight the effectiveness of Dy2Ce2O7 nanostructures in enhancing the barrier, thermal, mechanical, and UV-resistant properties of WS/SSG-based films, positioning them as promising materials for sustainable packaging applications.
