Mechanical and thermal properties and cytotoxicity of Al₂O₃ nano particle-reinforced poly(ether-ether-ketone) for bone implants

Weak mechanical properties and mismatching of elastic modulus to human bone restricts the use of PEEK as a bone implant material. By introducing reinforcing particles in polymers, composite material properties could be tailored to meet specific design requirements. In this work, composite materials with PEEK as a matrix and Al2O3 as reinforcing fillers were prepared by an injection molding method. Subsequently, the effects of different particle...
