This work aims to investigate the effect of black seed fiber as a reinforcing material for the fabrication of cornstarch-basedbiocomposite. The casting procedure was applied to fabricate the biocomposite at different concentrations of black seedfiber (3%, 6%, and 9%) and plasticizer mixture of fructose and glycerol set at a proportion of 30% (1:1) for total weight. The biocomposite films were tested in terms of casting procedure physical, tensile, thermal, and morphological properties. Increasing the black seed fiber concentration from 3% to 9% decreased the density and moisture content of the films by15.67% and 29.04%, respectively, and soil burial tests showed that the films became less resistant to biodegradation. Onthe other hand, an increase in tensile strength (40%), Young’s modulus (26%), and crystallinity index (64%) were observedwhen 9% of black seed fiber was added, reflected in a consistent structure and outstanding matrix-reinforcement compatibility. It was also found that reinforced biocomposite exhibited better thermal stability and more intermolecular hydrogenbonding compared to the control film. Overall, the addition of black seed fiber as promising reinforcing material significantlyimproved the performance of the films, which may contribute to the development of the biopolymers industry in responseto both community needs and environmental issues.
