Abstract
This study examined the mechanical properties of composite films composed of chitosan, cellulose nanofibrils, and aspirin. This biomaterial has promising characteristics and holds potential for various applications. The composite material, which was synthesised using precise fabrication techniques, consists of chitosan as a biocompatible substrate, cellulose nanofibrils for enhancing structural integrity, and aspirin for additional therapeutic benefits. The composite material exhibited increased tensile strength, tensile modulus, and elongation at break. The experimental results demonstrate that the tensile strength and tensile modulus exhibit an upward trend as the loading of cellulose nanofibrils (CNFs) increases. This observation suggests a synergistic improvement in mechanical robustness, which can be attributed to the combined effects of chitosan and CNFs. A reduction in elongation at break was seen as the loading of CNFs increased. The adaptability of the material is further emphasised by its tensile modulus and elongation at break. This study presents opportunities for the development of sustainable packaging materials, as the biodegradable properties of chitosan and cellulose are in line with current environmental priorities. The composite films composed of chitosan, cellulose nanofibrils, and aspirin demonstrate a notable combination of mechanical robustness and therapeutic properties. This research establishes the foundation for future attempts in biomaterial design by introducing a versatile composite that has the potential to significantly influence various sectors, including materials science and healthcare.
