摘要

The objective of this work is to study the feasibility of reinforcing polymer composites by utilizing the biofibers from the agricultural residue of Moringa oleifera pod husks (MOPH). The chemical and physical properties of the fibers were comprehensively investigated to evaluate their potential as a filler in gelatin-based films. The effect of MOPH fiber concentrations of 0, 5, 10, and 15 wt% on the water vapor permeability (WVP), and mechanical and thermal properties of the gelatin-based films was studied. By incorporation of 10 wt% of the MOPH fibers in gelatin, the highest tensile strength and Young's modulus, and the lowest WVP properties were obtained. Scanning electron microscopy (SEM) photographs indicated good interfacial adhesion between the fibers and the gelatin matrix. TGA of the biocomposites revealed an improvement of thermal stability. Moreover, under accelerated weathering, the gelatin-MOPH-10% biocomposite degraded more slowly than the gelatin control. These results indicate that the MOPH fibers are a good reinforcing filler and may be useful for biocomposite applications.
