摘要
采用溶胶-凝胶法在医用小骨元针上修饰纳米TiO2/SiO2复合保护膜,研究了不同制备条件对修饰后的小骨元针在酸性和中型溶液中的电化学行为。实验发现,修饰后的小骨元针在3%NaCl溶液中的稳定性优于在1 mol/L H2SO4溶液,但是,变化规律相似。
The kirschner wire was modified by nano-TiO2/SiO2 composite protection film using sol-gel method. The electrochemical behavior of the kirschner wire modified by different layers of the composite coatings was characterized in acidic and natural solutions. The results indicated that the stability of the modified kirschner wire is better in 3 % NaCl solution than that in 1 mol/L H2SO4 solution even the protection properties are similar.
