| 摘 要： | 以乳酸为原料、辛酸亚锡为催化剂制备聚乳酸（PLA）；以PI。A、Sm、钛酸四正丁酯（TBT）为原料，采用溶胶凝胶法制备稀土Sm掺杂PLA／TiO2有机无机杂化材料。XPS分析结果显示了Sm的加入。动态凝血时间测定法测定结果表明。Sm的掺杂提高了PLA／TiO2的抗凝血能力，并且在加入量为wt0．6％时效果最佳。

| Abstract: | The poiyiactic acid （PLA） is prepared with lactic acid as the raw material and stannous octoatc as the catalyst; Using tetrabutyl titanate （TBT）, samarium （Sm） and PLA as the raw materials, Sin-doped PLA/TiO2 organic-inorganic hybrid material is synthesized by sol-gel method. XPS results show that Sm i- ons has doped. The determination results of dynamic cruor time mensuration show that the anticoagulation property has improved because of the Sm ions, and the addition of wt0. 6% has the best effect. |
