Investigation of Electrochemical Modification and Preparation of Bioactive Composite Coating on Titanium Surface [PDF]
钛及钛合金作为植入体材料具有优良的机械性能和生物相容性,但本身不具备生物活性,需要通过表面修饰改性使之具备诱导骨组织长入并与植入部位实现骨性结合的能力。目前已采用各种表面处理方法在钛及钛合金表面改性和制备生物活性陶瓷涂层。本文首先通过电化学阳极氧化工艺,在钛表面形成了具有多孔结构的陶瓷氧化膜,并结合XRD、SEM以及电化学交流阻抗等方法对其形貌、成分和结构进行了表征。在SBF中诱导沉积HAp,以期得到具有生物活性、可促进细胞的粘附和生长的表面形貌和结构。结果表明 ...

Preparation and biological property of Chitosan/Hydroxyapitate composite for internal fixation of bone fracture [PDF]
虽然传统的金属骨折内固定材料在骨折内固定中一直占据主导地位,但是也存在着应力遮挡作用、腐蚀引起的慢性炎症和诱发不良反应、需二次手术取出等不可避免的缺点。因此,从20世纪60年代开始,国内外许多学者开始投入可吸收骨折内固定材料的研究,并取得一定成绩。壳聚糖/羟基磷灰石复合材料由于其良好的生物相容性、骨传导性和骨诱导性在骨修复材料的研究中占据重要地位。但是,目前壳聚糖/羟基磷灰石复合材料存在力学性能不佳及随羟基磷灰石含量增加力学性能下降的问题,限制了其在骨折内固定材料方面的应用。 本文在原位沉析法的基础上 ...
