摘要:鈦及鈦合金是20世紀發展起來的一種特殊的功能金屬材料,鈦質量輕、比強度高、而且耐熱性高、耐腐蝕性好,很快地取代了鋁合金的地位,被科學界重點研究和廣泛應用。TiO2納米管由于其優良的電化學性能,穩定的物理化學性質,近年來吸引了很多研究人員的興趣。TiO2納米管制備的方法有很多,在許多制備方法當中,有的方法工藝過程復雜,有的對設備的要求比較高,而陽極氧化的制備方法工藝過程簡單,設備要求不高,大大降低了TiO2納米管的制備成本,而且該工藝已經逐漸成熟,能很好的控制TiO2納米管的形貌,得到的產品利用率更大。因此,鈦的陽極氧化技術得到了越來越廣泛的應用。34439
本文在之前學者研究的基礎上,改變鈦板的尺寸,改用鈦箔作為基體使納米管應用性外觀更薄更美觀。本文以鈦箔片為陽極,銅片為陰極,在一定濃度的氫氟酸溶液為電解液,通電后鈦表面進發生陽極氧化,制備得到TiO2納米管。在確定制備方法的基礎上,改變工藝參數,分別在10V、15V、20V、25V和30V電壓,0.1wt%、0.5wt%和1.0wt%的電解液濃度,氧化時間在10min、20min、30min和40min,溫度為10℃、20℃、25℃和30℃下進行實驗,比較得出的樣片,找出了最佳的工藝參數是是氧化電壓在20V下,0.5wt%電解液濃度,25℃和20min下得到的TiO2納米管管徑在50-80nm,排列有序。
科學界對于超疏水材料的研究已經有幾十年了,因其在抗氧化、防止電流傳導、防腐、防雪、自凈、微流體注射、防污染等方面有廣泛的應用前景,因此超疏水性材料被應用于工業農業和人的日常生活中。TiO2納米管因為表面有空洞因此屬于親水性,本文將TiO2納米管在硬脂酸中修飾后,改變了其接觸角,增大為160°變為超疏水性,增加了TiO2納米板的實用性能。 源¥自%六:維;論-文'網=www.aftnzs.live

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. 鈦箔陽極氧化工藝研究:http://www.aftnzs.live/huaxue/20190412/31934.html
