Assisted hydrothermal synthesis of green mussel shell-derived hydroxyapatite for use in filler polymer-based composites

Abstract Biodegradable bone implants based on bio-composite of polylactic acid and polycaprolactone biopolymers with hydroxyapatite are available and have significantly increased the usage of biomaterials in the medical industry. This study developed bio-composites of polylactic acid, polycaprolactone, and hydroxyapatite. The bio-composite made from a blend of 60% PCL and 40% PLA was with various quantities of hydroxyapatite, ranging from 5%, 10%, 15%, and 20% by weight. During the chemical blending procedure, chloroform was a solvent. The following evaluating tests included SEM, XRD, FTIR, microhardness, tensile and density Tests, and Biodegradation Tests. The chemical blending procedure could convert PCL, PLA, and hydroxyapatite materials into bio-composite materials. The presence of hydroxyapatite increased both the hardness and density of the bio-composite. The three materials are mechanically linked to prevent any new phases from being revealed by SEM, XRD, or FTIR examination. Materials that contain more hydroxyapatite dissolve more quickly when submerged in NaCl solution.
