本研究使用Nd:YAG脈衝雷射在鈦金屬基材上製備二氧化鈦(TiO2)材料。藉由改變雷射功率及脈衝時間,獲得不同比例的銳鈦礦(anatase)與金紅石(rutile)的TiO2。材料的表面形貌、結晶型態、反射率以及親疏水特性分別使用光學顯微鏡、SEM電子顯微鏡、X光粉末繞射分析儀(XRD)、UV-VIS-NIR光譜儀以及接觸角量測儀進行量測與分析。最後藉由上述量測與分析結果搭配甲基藍(MB)光催化降解實驗選出最佳的製程參數。研究結果顯示,試片表層依據不同脈衝功率出現不同型態的裂痕。低功率條件下的試片表面出現黃、藍、紅等多種顏色,高功率試片則呈現灰色。XRD分析發現試片表層主要含有anatase、rutile與TiN等三種結晶型態的成分。所有試片表面最大反射率發生在波長310 nm。各試片在CIE 1931色度座標中的(x, y)座標差異很小,y軸變化率會隨著脈衝時間的增加而逐漸下降的趨勢。不同照射波長對於試片表面照射前後之水滴接觸角度並無明顯變化。照光波長380 nm情況下多數試片的MB降解率明顯高於鈦金屬基材,然而在413 nm與460 nm照射之下則差異較小。照光波長在380 nm、413 nm以及460 nm的最高MB降解率分別為18.7%、15.1%以及9.8%降解率。所有波長中MB降解率越高其anatase重量比率也越高;rutile在380與413 nm波長中的MB降解率越高則重量比則是越少,460 nm波長中的MB降解率越高則重量比則是越多;TiN對於MB降解率的影響趨勢則與Rutile相同。380 nm與413 nm照光波長呈現雷射能量在6 mJ到40 mJ區間具有較佳的光催化效果;413 nm與460 nm照光波長則呈現雷射能量在16 mJ到70 mJ具有較佳的可見光光催化效果。
In this study, titanium dioxide (TiO2) with different proportions of anatase and rutile was prepared on a titanium substrate using Nd: YAG pulsed laser with various laser powers (6-14 W) and pulse durations (1-5 ms). The surface morphology, crystallization, reflectivity, and hydrophilic/hydrophobic properties of the specimen were measured and analyzed using an optical microscope (OM), scanning electron microscope (SEM), X-ray diffractometer (XRD), UV-VIS-NIR spectrometer, and contact angle measuring instrument. Finally, the optimum process parameters were selected by the above-mentioned measurement and analysis results with methyl blue (MB) photocatalytic degradation experiments. The results showed that the surface of the specimen appeared different types of cracks with various laser powers. The colors of yellow, blue, and red appeared on the surface of the specimen that manufactured using lower laser power, and the colors of gray appeared on the surface of the specimen that manufactured using higher laser power. XRD analysis revealed that the surface of the specimen mainly contained three kinds of crystalline forms such as anatase, rutile and TiN. The maximum reflectivity of the entire specimen surface occurred at a wavelength of 310 nm. The difference on the (x, y) coordinates of the specimen in the CIE 1931 chromaticity coordinates were very small, and the change rate of y-axis will decrease with increasing the pulse duration. There was no significant change in the contact angle of water droplets on the specimen surface before and after irradiation with various irradiation wavelengths. The degradation rate of MB was higher than that of titanium substrate at 380 nm, but the difference was less at 413 nm and 460 nm. The highest degradation rates of MB with irradiation wavelength at 380 nm, 413 nm and 460 nm were 18.7%, 15.1% and 9.8% respectively. The degradation rate of MB increased with increasing the weight ratio of anatase in all irradiation wavelengths, the degradation rate of MB increased with decreasing the weight ratio of rutile in the irradiation wavelength of 380 and 413 nm, but showed the opposite trend in the 460 nm. The effect of TiN on MB degradation rate was the same as that of rutile. The laser energy of 6 to 40 mJ had a better photocatalytic effect in the irradiation wavelength of 380 and 413 nm. The laser energy of 16 to 70 mJ had a preferred visible light photocatalytic effect in the irradiation wavelength of 413 and 460 nm.
