【摘要】：采用電化學陽極氧化法,以含有0.25wt%NH4F和2mL H_2O的乙二醇溶液作為電解液制備了TiO_2納米管陣列,然后通過不同溫度退火比較其形貌、結構、元素組成和親水性能。實驗表明,600℃以下溫度退火基本不會引起TiO_2納米管陣列的形貌改變,但是600℃退火會使得部分TiO_2納米管坍塌。隨著退火溫度的升高,TiO_2由無定型結構向晶體結構轉變,同時接觸角減小,親水性變好。另一方面,F元素也會影響TiO_2納米管陣列的親水性能,F元素含量越少,親水性越好。
[Abstract]:TIO _ 2 nanotube arrays were prepared by electrochemical anodic oxidation with ethylene glycol solution containing 0.25 wtNH _ 4F and 2 mL H _ 2O as electrolyte. The morphology, structure, elemental composition and hydrophilicity were compared by annealing at different temperatures. The experimental results show that annealing temperature below 600 鈩，
