摘要：钛及钛合金是20世纪发展起来的一种特殊的功能金属材料，钛质量轻、比强度高、而且耐热性高、耐腐蚀性好，很快地取代了铝合金的地位，被科学界重点研究和广泛应用。TiO2纳米管由于其优良的电化学性能，稳定的物理化学性质，近年来吸引了很多研究人员的兴趣。TiO2纳米管制备的方法有很多，在许多制备方法当中，有的方法工艺过程复杂，有的对设备的要求比较高，而阳极氧化的制备方法工艺过程简单，设备要求不高，大大降低了TiO2纳米管的制备成本，而且该工艺已经逐渐成熟，能很好的控制TiO2纳米管的形貌，得到的产品利用率更大。因此，钛的阳极氧化技术得到了越来越广泛的应用。34439
本文在之前学者研究的基础上，改变钛板的尺寸，改用钛箔作为基体使纳米管应用性外观更薄更美观。本文以钛箔片为阳极，铜片为阴极，在一定浓度的氢氟酸溶液为电解液，通电后钛表面进发生阳极氧化，制备得到TiO2纳米管。在确定制备方法的基础上，改变工艺参数，分别在10V、15V、20V、25V和30V电压，0.1wt%、0.5wt%和1.0wt%的电解液浓度，氧化时间在10min、20min、30min和40min，温度为10℃、20℃、25℃和30℃下进行实验，比较得出的样片，找出了最佳的工艺参数是是氧化电压在20V下，0.5wt%电解液浓度，25℃和20min下得到的TiO2纳米管管径在50-80nm，排列有序。
科学界对于超疏水材料的研究已经有几十年了，因其在抗氧化、防止电流传导、防腐、防雪、自净、微流体注射、防污染等方面有广泛的应用前景，因此超疏水性材料被应用于工业农业和人的日常生活中。TiO2纳米管因为表面有空洞因此属于亲水性，本文将TiO2纳米管在硬脂酸中修饰后，改变了其接触角，增大为160°变为超疏水性，增加了TiO2纳米板的实用性能。

The Study on Anodic Oxidation Technology of Titanium Foil
Abstract：Titanium and titanium alloy is a special feature metal materials developed in the 20th century, titanium light weight, high strength, and high heat resistance, corrosion resistance, and soon replaced the aluminum alloy, the scientific community key research and widely used. TiO2 nano-tubes due to their excellent electro-chemical performance, stable physical and chemical properties, in recent years attracted the interest of many researchers. There are many ways to control nano-TiO2 prepared in many preparation methods, the process is complicated and some method, some of the equipment is relatively high, and the preparation of anodic oxidation process is simple, less demanding equipment, greatly reduces the TiO2 the cost of preparation of nano-tubes, and the process has matured, can be well controlled morphology TiO2 nano-tubes obtained greater product utilization. Thus, titanium anodizing technology has been more widely used.
Based on prior research scholars, change the sizes of titanium, titanium foil as the substrate instead make use of nano-tubes look thinner and more beautiful. In this paper, a titanium foil anode, copper cathode, at a certain concentration of hydro-fluoric acid solution as an electrolyte, the titanium surface into electricity after anodization prepared TiO2 nano-tubes. Determining, based on the production method, changing the process parameters, respectively 10V, 15V, 20V, 25V and 30V voltage, 0.1wt%, 0.5wt% and 1.0wt% of the electrolyte concentration, the oxidation time 10min, 20min, 30min, and 40min, temperature is 10℃，20℃, 25℃ and 30℃, relatively derived samples, to find the best process parameters is oxidized voltage under 20V, 0.5wt% electrolyte concentration, 25℃ and 20min obtained under TiO2 nano-tube diameter in 50-80nm, arranged in order.
The scientific community for research super-hydrophobic materials has been for decades, and its antioxidant, preventing current conduction, corrosion, anti snow, self-purification, micro-fluid injection, pollution and other aspects of a wide range of applications, so super hydrophobic materials It is used in industrial agriculture and people's daily life. TiO2 nano-tubes because the surface has a hydrophilic hollow Therefore, this article TiO2 nano-tubes after modification in stearic acid, changing the contact angle increased to 160°becomes super-hydrophobic increase the utility of TiO2 board performance. 钛箔阳极氧化工艺研究:http://www.youerw.com/huaxue/lunwen_31934.html
