摘要: 采用“交替循环浸泡法(ALIM)”在TiO2纳米管管内填充类骨磷灰石, 使磷灰石涂层由层状结构变为嵌入式结构, 并考察填充量与TiO2纳米管结构间的关系, 通过模拟体液浸泡实验评价其生物活性. 结果表明, 甘油体系(60V电压)中制备的纳米管填充效果最好; 无定型的TiO2纳米管相比锐钛矿相的TiO2纳米管更能诱导类骨磷灰石的填充; 采用ALIM于TiO2纳米管上填充类骨磷灰石可大大提高其生物活性.

Abstract: A vertically aligned TiO2 nanotube array was fabricated on the surfaceof titanium substrate in fluoride-containing electrolyes by anodization. Alternative Loop Immersion Method(ALIM) was investigated to fill TiO2 nanotubes with the biologicalapatite in the saturated solution of Ca(OH)2 and 0.02 mol/L (NH4)2HPO4.In this way, the structure of the apatite-coating on the Ti substrate waschanged for solving the problem of coating shedding well. And the amount ofsynthetic apatite formed by ALIM was quantified according to key tubeproperties such as the tube diameter, the layer thickness, the crystalstructure (amorphous or anatase), <>etc. The effect of filling biologicalapatite of TiO2 nanotubes fabricated in glycerol-based electrolyteat 60V is the best. And the rate of inducing biological apatite on amorphous TiO2nanotubes with the treatment of ALIM is better than that of anatase TiO2nanotubes. Mineralization <>in vitro experiments indicates that TiO2nanotubes after ALIM treatment promote natural apatite formation significantlyin a simulated body fluid (SBF). Such TiO2 nanotube arrays with ALIMtreatment, are useful as a well-adhered bioactive surface layer on Ti implantmetals for orthopaedic and dental implants.
