中文摘要:超高分子量聚乙烯人工关节的摩擦磨损是导致人工关节失效的主要原因之一。根据表面改性方法的机理,采用多种改性方法使超高分子量聚乙烯减摩抗磨性能得到了提高,同时对超高分子量聚乙烯材料的内部结构和性能未造成损害;在工艺上,表面改性方法的工艺条件易于控制,操作简单。但是,辐射交联反应时间过长,材料会氧化脆裂;表面接枝的单体自身均聚严重;离子注入方法的注入层很薄,容易被破坏,仍需要进一步改善。为优化超高分子量聚乙烯人工替换关节耐磨性能的研究提供参考。目前,对该材料研究主要在耐磨性、关节面磨屑问题、强度等方面,同时在临床试验中的应用也一直是研究的焦点,具有广阔的发展前景。

Effect of surface modification on biotribological properties of ultra-high molecular weight polyethylene artificial joints
ABSTRACT  Friction and wear of ultra-high molecular weight polyethylene is a major cause of artificial joint failure. According to mechanism of surface modification method,friction reduction and wear-resistance properties of UHMWPE were improve by several kinds of surface modification methods. Meanwhile,this do not damage the internal structure and properties of UHMWPE. In the process,condition is easy to control and operation is simple. However,reaction time of radiation crosslinking method is too long,the material will be oxidized embrittlement;Monomer itself homopolymerization are seriously in the process of surface grafting;The injection layer of ion implantation methods is very thin and easy to be destroyed. Objective in order to provide a reference for further research on the biotribological properties of ultra-high molecular weight polyethylene artificial joints. At present,as the researches of UHMWPE material main focus on abrasion resistance,and application in the clinical trial is the focus of research,it has a wide prospect in the future.
