Application of polydopamine coating in polyetheretherketone modification

Abstract

Poly-ether-ether-ketone (PEEK), a new type of bone implant, as a substitute for titanium and other traditional bone implants, its clinical application is affected by its surface hydrophobicity and biological inertia. The research on the improvement of osteogenesis and antibacterial activity of PEEK has attracted more and more attention. Polydopamine (PDA) coating, a widely used surface modification coating, is used to modify PEEK, which can not only solve the problem of low surface activity of PEEK, but also maintain the good mechanical properties of PEEK. In this paper, the articles of surface modification of PEEK with polydopamine coating are summarized and reviewed.
