文章编号: 1004-0609(2004)09-1575-05 NiTi形状记忆合金表面TiO2薄膜的制备及其血液相容性 耿芳1, 石萍1, F. T. Cheng2 (1. 辽宁工学院 材料与化学工程学院, 锦州 121001; 2. Department of Applied Physics, Hong Kong Polytechnic University, Hong Kong, China) 摘 要: 采用溶胶-凝胶法在NiTi合金表面制备了TiO2薄膜, 用DSC分析了凝胶在加热过程中发生的转变. 结果表明: 在NiTi表面形成金红石型TiO2薄膜; 覆盖有TiO2薄膜的NiTi合金与NiTi基体及316L不锈钢, Ti6Al4V相比, 凝血时间延长, 溶血率下降, 说明TiO2膜可提高NiTi合金血液相容性. 关键词: NiTi; 溶血; 凝血......

文章编号:1004-0609(2009)05-0910-09 S与金属共掺杂TiO2催化剂的制备及其光催化性能 顾凌燕1,王玉萍1,2,彭盘英1,王连军2 (1. 南京师范大学 化学与环境科学学院,南京 210097; 2. 南京理工大学 化工学院,南京 210094) 摘 要:采用溶胶-凝胶法制备S,Mo,Pt,Fe掺杂以及S/Mo,S/Fe,S/Ag共掺杂的TiO2粉末,利用XRD,XPS和UV-Vis等技术对样品进行表征;以1-萘酚-5-硫酸(L-酸)为目标物,考查紫外和可见光源下各催化剂的光催化活性.结果表明:除S/Ag-TiO2外,其余掺杂TiO2均为单一的锐钛矿相,掺杂后催化剂的吸收带边发生明显红移;对10 mg/L的L-酸进行降解,在可见光下,S-TiO2光催化活性较好,而在紫外光下,S/Ag-TiO2的光催化活性较好;经XPS分析发现,掺杂元素掺入到......
