Surface modified PEEK/BG composite for bone regeneration
Supervisors: Zhiyan Xu, Prof. Aldo R. Boccaccini
Polyetheretherketone (PEEK) is a polyaromatic semi-crystalline thermoplastic with favorable mechanical properties for bio-medical applications . It exhibits biocompatibility, and resistance to corrosion. However, PEEK is bioinert, lacking osseointegration after implantation, which leads to a higher a chance of implant failure. Mesoporous bioactive glass nanoparticles (MBGNs) prepared by sol-gel method have attracted much attention in the field of tissue regeneration due to their customizable microstructures and chemical composition . In this project, a PEEK/MBGNs composite will be fabricated. To further improve the osteoinductive and antimicrobial capabilities, different types of surface functionalization on PEEK/MBGNs composites will be investigated.
