Metal-organic frameworks/polydopamine coating endows polyetheretherketone with disinfection and osteogenicity

The work describes a polydopamine-wrapped zeolitic imidazolate framework-8 (ZIF-8) coating constructed on the sulfonated polyetheretherketone (PEEK). The coating is not only conducive to the controllable Zn2+ releases, but also exhibits excellent photothermal capacity under near-infrared (NIR) irradiation. in vitro antibacterial experiments indicate the coating possesses bactericidal efficiencies of 100% against Staphylococcus aureus and...
