Embodiment 1
[0024] Preparation of silver-containing titania nanofilms on pure titanium surface by hydrothermal treatment of silver nitrate solution
[0025] Pure titanium sheet with a thickness of 1.2mm and a size of 10×10mm 2 , polished step by step with No. 180, 500, 800, and 1200 sandpaper, and ultrasonically cleaned with acetone, ethanol, and pure water for 10 minutes. Prepare a 10mmol / L silver nitrate solution and add it to a polytetrafluoroethylene-lined hydrothermal kettle with a filling rate of 70%. Put the titanium sheet in the hydrothermal kettle. Airtight and hydrothermal treatment at 200°C for 12 hours. After the reaction, the samples were taken out, rinsed several times with pure water, and dried for later use. Such as figure 1 As shown, the surface of pure titanium after hydrothermal treatment forms 50-130nm particles. Silver was detected by X-ray photoelectron spectroscopy. After the sample was exposed to ultraviolet light for 60 minutes, the water contact angle decrea...

[0027] Preparation of silver-containing titania nanofilms on pure titanium surface by hydrothermal treatment of silver nitrate solution
[0028] Pure titanium sheet with a thickness of 1.2mm and a size of 10×10mm 2 , polished step by step with No. 180, 500, 800, and 1200 sandpaper, and ultrasonically cleaned with acetone, ethanol, and pure water for 10 minutes. Prepare a 20mmol / L silver nitrate solution and add it to a polytetrafluoroethylene-lined hydrothermal kettle with a filling rate of 70%. Put the titanium sheet in the hydrothermal kettle. Closed and hydrothermally treated at 150°C for 24 hours. After the reaction, the samples were taken out, rinsed several times with pure water, and dried for later use. Such as figure 2 As shown, after hydrothermal treatment of pure titanium, small particles of 30-50nm and needle crystals with a width of about 50nm and a length of 600nm are formed on the surface. Silver was detected by electron spectroscopy.
Embodiment 3
[0030] Preparation of silver-containing titania nanofilms by hydrothermal treatment of titanium alloy TLM (Ti-25Nb-3Zr-2Sn-3Mo) with silver nitrate solution
[0031] A titanium alloy TLM sheet with a thickness of 0.6mm is used, and the size is 10×10mm 2 , polished step by step with No. 180, 500, 800, and 1200 sandpaper, and ultrasonically cleaned with acetone, ethanol, and pure water for 5 minutes. Prepare 10mmolL of silver nitrate solution and add it to a polytetrafluoroethylene-lined hydrothermal kettle with a filling rate of 80%. Put the titanium alloy sheet in the hydrothermal kettle. Airtight and hydrothermal treatment at 200°C for 12 hours. After the reaction, the samples were taken out, rinsed several times with pure water, and dried for later use. Such as image 3 As shown, after the hydrothermal treatment of the titanium alloy TLM, small particles of about 50 nm and rhombohedral crystals with a width of about 150 nm and a length of 400 nm were formed on the surface...
