Polymer nanocomposites for load-bearing implant applications

Original language description

The development of advanced biomaterials for load-bearing implant applications is critical for improving and increasing their performance and longevity. This study comprises the fabrication and testing polymer composites made of UltraHigh Molecular Weight Polyethylene (UHMWPE) and Barium Titanate (BaTiO3) nanoparticles for use in load-bearing biomedical implants. Five combinations of UHMWPE and BaTiO3 were created using compression molding processes, to evaluate the pertinence of the composite. The BaTiO3 amount varied between 0-10 wt%. The composites were then subjected to comprehensive mechanical, surface, and tribological characterization studies. The mechanical properties of the UHMWPE-BaTiO3 composites were evaluated through tensile strength, flexural strength, and impact resistance tests. Additionally, hardness testing was conducted to evaluate the materials´resistance to deformation and wear. Contact angle measurements were utilized to analyze the surface wettability of the composites, which provided insights into their interaction with biological fluids. The tribological testing was conducted using a pin-on-disc tribometer to explore the friction and wear behavior, which is essential for predicting their performance under load-bearing conditions. The composites were further characterized by light microscopy, X-ray Diffraction (XRD), and Differential Scanning Calorimetry (DSC). The study reveals the potential of UHMWPE-BaTiO3 composites as biomedical implant materials due to their improved mechanical strength, hardness, and tribological properties. However, further evaluation is necessary to determine their biocompatibility and applicability for biomedical applications
