采用电泳沉积的方法在医用金属钛表面沉积纳米羟基磷灰石(HA)/多壁碳纳米管(MWCNTs)复合涂层.力学拉伸实验表明,所制备的纳米HA与MWCNTs的复合涂层可显著增强其与基底材料的结合力.体外细胞培养试验证明,电泳沉积制备的复合涂层具有良好的生物相容性.可望成为一种新的综合性能良好的硬组织生物材料.In order to enhance the bonding strength of hydroxyapatite (HA) coating to a metal substrate,and also improve its biocompatibility,the electrophoretic deposition(EPD) technique has been developed to prepare a composite coating of HA/multi-walled carbon nanotubes(MWCNTs) on a titanium substrate.It is indicated that after sintering at 700℃ for 2 h the adhesive strength of the prepared composite coating to the titanium substrate is increased as high as 35.44 MPa.And it is also demostrated,in vitro cell culture test,that the HA/MWCNTs composite coating is of a good biocompatibility.It is promising to develop a new hard tissue biomaterial with satisfied mechanical and biological properties.国家自然科学基金(20273055);; 教育部博士点基金(20020384012);; 国家863计划(2003AA302230);; 福建省科技重大项目(2003I001)资
