Popis: In order to improve the mechanical properties of HA/PEEK composite, the surface modification of nanosized hydroxyapatite (n-HA) was carried out with silane coupling agent (SCA).The modified particles were produced using different contents of SCA (KH560) and characterized by virtue of Fourier Transform Infrared (FT-IR) spectroscopy. The polyetheretherketone (PEEK) nanocomposite materials reinforced by surface-modified n-HA were successfully prepared and their microstructure and mechanical properties were examined by scanning electron microscopy (SEM), Instron IX Material Testing System and Vickers micro-hardness tester. The result of FT-IR indicated that the nanosized HA was coupled with the SCA by a chemical bonding. SEM observation showed that SCA-HA was well-dispersed in PEEK matrix. The results incicated that mechanical strength of SCA-HA/PEEK composite was improved and best at 5 vol.% HA, 3wt.% SCA.Keywords: nanosized hydroxyapatite; Silane couping agent; Polyetheretherketone; Biocomposite; Mechanical propertity
