PEEK/HA生物复合材料的热稳定性
Thermal stability of PEEK/HA biological composite materials
摘要
Abstract
Based on the polycondensation of polyetheretherketone, by adding hydroxyapatite blended into (polyetheretherketone, PEEK) , biological composite materials were prepared. Therraogravimetric analysis was conducted to study the thermal stability of the composite materials. Results show that the thermal decomposition temperatures are above 500 ℃ in the beginning, showing desirable thermal stability. Heating rates have an important influence on thermogravimetric curves. Further, as heatings speed up, thermogravimetric curves move to a high temperature, and the initial decomposition temperature and maximum thermal decomposition temperature increase. Also, maximum decomposition rate decreases with the increase of HA content, indicating that the thermal stability of PEEK/HA composites are better than that of PEEK. A cytotoxicity test shows that PEEK/HA composites have no significant toxicity to Hela cells, and they promote cell growth, showing that the biological compatibility of PEEK/HA composites is good.关键词
