Investigation of Water Absorption and Porosity of Nano-Biosilica, Jute, and Bamboo Fiber-Reinforced Chitosan Biocomposite Materials

This study investigates water absorption and porosity in the chitosan matrix reinforced with nano-biosilica, bamboo fiber, and jute fiber used for long bone material implants. The water absorption tests reveal distinct patterns in CP, CF, C1, C2, and C3 biocomposites, thereby highlighting the influence of their composition. Notably, 1% nano-biosilica reduces water absorption, yet increased nano-silica concentrations lead to heightened porosity. Striking a balance between optimal porosity for osseointegration and mechanical strength is crucial. Hybridization proves effective in mitigating water uptake and porosity. This study advances knowledge in biomaterial intricacies, providing crucial insights for tailored implant design.
