BaTiO3 /UHMWPE Composites for Enhanced Performance in Load-Bearing Biomedical Implants

Original language description

The pursuit of advanced biomaterials for load- bearing applications in biomedical implants has incited the development of polymer composites tailored for optimal mechanical properties, wear resistance, and biocompatibility. This research emphases on the development and characterization of polymer composites based on Ultra-High Molecular Weight Polyethylene (UHMWPE) reinforced with Barium Titanate (BaTiO3) nanoparticles. In order to assess the suitability of the composite for load-bearing biomedical implants, five distinct combinations of UHMWPE and BaTiO3 were fabricated by with compression molding process (0, 2.5, 5, 7.5, and 10% wt.) and tested with mechanical, surface, and tribological studies. The mechanical behaviour of the UHMWPE-BaTiO3 composites indicates enhancements intensile strength, flexural strength, and impactresistance, crucial for ensuring the mechanicalintegrity required in load-bearing applications. The surface wettability of the composites was analysed with the Contact angle measurements, provided insights into their interaction with biological fluids. Hardness testing was employed to assess the materials’ resistance to deformation and wear. Tribological testing, using a pin-on-disc tribometer, explored the friction and wear behaviour, essential for predicting their performance within the human body under load-bearing conditions. The composites were characterized by light microscopy, X-ray Diffraction (XRD), Atomic Force Microscopy (AFM) and Differential Scanning Calorimetry (DSC). The study reveals the potential of UHMWPE- BaTiO3 composites as biomedical implant materials due to their mechanical strength, hardness, and tribological properties. These composites are suitable for structural integrity and reduced wear applications. Their biocompatibility and therefore applicability for biomedical applications must be further evaluated.
