| 摘 要： | 为了改善硬组织修复用三维编织碳纤维增强聚醚醚酮(3D C/PEEK)复合材料的生物活性, 采用空气等离子体处理技术对其进行表面预处理, 随后浸入1.5倍模拟体液(SBF)中进行仿生沉积, 研究了等离子体处理时间对表面形貌、 亲水性、 表面化学态以及仿生沉积效果的影响。结果表明, 随着等离子体处理时间的延长, 3D C/PEEK复合材料表面粗糙度增加, 表面亲水性得到明显改善, 同时表面极性官能团数量增加。经过等离子处理后的3D C/PEEK复合材料试样浸入1.5倍SBF中7天后, 两种处理时间的复合材料表面均有沉积层生成, 且经过120 s处理的复合材料表面沉积层更加致密均匀, EDS分析证实沉积层为钙磷化合物。

| Abstract: | In order to improve the bioactivity of the 3D braided carbon fiber reinforced PEEK composites(3D C/PEEK) used for high-performance hard tissue repair materials,the air plasma technology was used to treat the surface of the 3D C/PEEK,and then Ca-P layer on their surface was obtained through immersing in 1.5 times simulated body fluid(SBF) for 7 days.The effect of plasma treatment time on the surface appearance,hydrophility,chemical characterization and biomimetic deposition of the 3D C/PEEK was studied.The r... |
