采用阳极氧化法制备 TiO2纳米管阵列，研究电解液成分、阳极氧化电压、阳极氧化时间、电解液温度及氧化次数对纳米管阵列微观结构及形貌的影响，探讨了TiO2纳米管阵列生长机理，并采用 SEM、表面粗糙度仪、接触角测量仪对所得 TiO2纳米管阵列的形貌、粗糙度、亲水性及表面能进行了表征和分析。结果表明，阳极氧化后 Ti 表面活性增加，相比于其他阳极氧化工艺参数，电解液成分对样品表面粗糙度、接触角及表面能的影响更大。
The aligned TiO2 nanotube arrays on Ti substrate were fabricated in different electrolytes by means of anodization.The effects of electrolyte components,voltage and reaction time on the morphology and micro-structure of TiO2 nanotube arrays were investigated in this study,and the growth mechanism of TiO2 nanotube arrays was also discussed.Besides,the nanostructure,morphology,hydrophilicity,roughness and surface en-ergy of the TiO2 nanotubes were characterized and analyzed using SEM,surface roughness tester and water con-tact angle testing.The results showed that,the diameter,length,morphology,roughness,hydrophilicity and surface energy of TiO2 nanotubes have changed in different anodization processing parameters,in which the effect of the electrolyte component was most obvious.
