APATITE-POLY(ETHER ETHERKETONE) NANO COMPOSITES: PROSTHESIS MATERIALS: SBF-CONDITIONED STUDY

摘要

A prosthesis material using calcium phosphates-poly(ether etherketone)thermoplastic nano composite was developed. The nanosized calcium phosphates were synthesized by sol-gel technique. The biocompatibility test was carried out by SBF-conditioned study using freshly prepared simulated body fluid (SBF) at a temperature of 25-40℃ and pH of 6.5-7.7. XRD was used to see the crystallinity and composition. The morphology and component distribution were performed by OM, SEM, AFM, etc. The functional groups present in composite materials were evaluated by FTIR. The growth study of SBF crystal was carried out by OM and XRD. The porous microsphere of Hap-PEEK composite was observed in SEM.
