Research on the Preparation of HA/PEEK Gradient Composites by Impregnation Method and the Biosecurity

Abstract:

This study prepares the HA/PEEK gradient composites with special structural design by impregnation method, which eases the contradiction of the HA/PEEK composites between the lack of bioactivity due to low HA contents and the poor mechanical properties due to high HA contents, and effectively improves the bioactivity and mechanical properties of the PEEK-based materials, and then evaluates the biosecurity of HA/PEEK gradient composites. The main functional cell of bone formation—osteoblast is adopted for the co-culture with PEEK, HA/PEEK gradient composites and the leach liquor, and the effects of PEEK and HA/PEEK gradient composites on the proliferative functions of osteoblast are studied by in vitro cytotoxicity test. The results show that no harmful admixtures are produced in the process of injection moulding, and the leach liquors of PEEK and HA/PEEK gradient composites have no effects on the proliferative functions of osteoblast, with good osteoblast compatibility.
