The Effect of Bath Temperature on the Adhesive Strength and Bioactivity of TiO2 Nanotube Arrays

摘要：

　　The effect of bath temperature on the morphologies,crystallographic structure and adhesive strength of TiO2 nanotube arrays fabricated by electrochemical anodization of titanium in dimethyl sulfoxide containing hydrofluoric acid electrolyte were studied in this paper.The results show that the crystalline anatase TiO2 nanotube arrays can be directly fabricated at the bath temperature above 50℃ without further annealing.The crystallinity ofanatase at the top ofnanotubes is higher than that at the bottom of nanotubes.The bath temperature has obviously impact on the surface morphology of the titanium substrate underneath the nanotube arrays.The adhesive strength of TiO2 nanotube arrays increases with the rise of bath temperature increasing,and reaches 11.3 MPa when TiO2 nanotube arrays are fabricated at 60 ℃.
