Fabrication of Mg Coating on PEEK and Antibacterial Evaluation for Bone Application

Polyetheretherketone (PEEK) is an alternative biomedical polymer material to traditional metal and ceramic biomaterials. However, as a bioinert material, its wide application in the medical field seriously restricted due lack of bioactivity. In this research, pure Mg was successfully deposited on PEEK substrate by vapor deposition improve antibacterial properties implants. The morphology elemental composition coating were characterized scanning electron microscopy (SEM) energy-dispersive spectroscopy (EDS). higher temperature, larger particle size. possesses hydrophilic surface free energy that create good biocompatibility. withstands up 56 days’ immersion. test showed rate coated 99%. Mg-coated demonstrates promising properties.
