Abstract
Problem definition and objectives: The aim of this research is the investigation of the physical and mechanical properties of polycaprolactone biocomposite and banana fibre reinforced with nano chitosan polymer for the improvement and development of biodegradable composites.
Methodology: In this study, bio-composites were prepared by combining poly caprolactone (PCL) granules with treated banana fibers (using a 10% sodium hydroxide solution) and untreated banana fibers. Additionally, 0.5%, 1%, and 2% nano-polymer chitosan were added to the composites. Subsequently, physical, mechanical, FTIR spectroscopy, thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM) tests were conducted.
Results: The results indicate that chemical modification of banana fibers significantly improves the properties of wood-plastic composites. Increased density, reduced water absorption, and enhanced thickness swelling demonstrate the positive effects of these modifications. Furthermore, the addition of nano-polymer chitosan significantly improves flexural strength. Spectroscopic and thermal weight analysis confirm that chemical treatment and the inclusion of chitosan positively impact the stability and thermal properties of the composites.
Conclusion: Overall, this research highlights that chemical modifications and the addition of nano-polymer chitosan can lead to substantial improvements in the properties of wood-plastic composites, making them suitable options for various industrial applications.
