Synthesis and Characterization of Silver –doped Hydroxyapatite-Coated Polyether ether ketone for Dental Applications

The main objective of this paper is to develop and characterize silver-doped hydroxyapatite (Ag-HA) coating on Polyether ether ketone (PEEK). The physicochemical characteristic of Ag-HA coated on PEEK was evaluated by X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), and also determining calcium (Ca) / phosphorus (P) ratio and silver (Ag) / calcium (Ca) ratio by inductive coupled plasma atomic emission spectroscopy (ICP-AES). The surface morphology of Ag-HA coated on PEEK was analyzed by scanning electron microscopy (SEM). XRD, FTIR, and ICP-AES analysis of the coated layer confirms Ag-HA deposition on PEEK, the Ag successfully substitutes Ca in the hydroxyapatite (HA) lattice. The Ag substitution is not 100 % as compared with the initial added Ag. Surface morphology analysis of Ag-HA-coated PEEK reveals the flake structure of Ag-HA formation on PEEK.
