【Abstract】 The aligned TiO2nanotube 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 microstructure of TiO2nanotube arrays were investigated in this study,and the growth mechanism of TiO2nanotube arrays was also discussed.Besides,the nanostructure,morphology,hydrophilicity,roughness and surface energy of the TiO2nanotubes were characterized and analyzed using SEM,surface roughness tester and water contact 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.更多还原
