本研究選擇含鋯銅鋁鎳組成之金屬玻璃作為光熱轉換材料。濾紙基材為水通道載體，在上方以不同射頻磁控濺鍍時間（1、3、5小時）做出鍍有金屬玻璃的 fp1、fp3、fp5樣品。開發漂浮型太陽能水蒸發系統，以作為海水淡化之應用。fp1、fp3、fp5樣品全都會漂浮在水面上，三種樣品仍然維持有開放孔結構，可以作為漂浮型太陽能水蒸發系統。
以XPS全譜分析與縱深分析探討金屬玻璃薄膜表面與不同深度之化學組成；毛細管流動分析儀分析複合薄膜之孔洞尺寸分布；水接觸角顯示表面潤濕性；由UV-Vis/NIR光譜儀評估光學性質；拉伸試驗評估機械強度耐用性。探討金屬玻璃濺鍍時間對多孔通道之孔洞尺寸分布、表面潤濕性、吸光性、機械強度、表面與不同深度之化學組成之影響。
在溫度20-22°C及相對濕度60-65% 的條件下，太陽能水蒸發效能實驗結果顯示蒸發速率和光熱轉換效率均隨濺鍍時間而增加 (fp5 > fp3 > fp1 > fp0) 。以 fp5 在氙燈照射下蒸發去離子水揮發速率為 849 g-m-2-h-1 ，光熱轉換效率可以達到66%。氙燈照射下蒸發模擬海水，fp5之揮發速率為685 g-m-2-h-1；光熱轉換效率可以達到53%。此外在不同環境下，分別以自製的太陽能蒸發器進行模擬海水蒸發試驗，探討模擬海水之冷凝淨水收集速率。室內氙燈照射下以及戶外太陽光照射下，fp5之冷凝淨水收集速率分別可達 414 g-m-2-h-1 與 593 g-m-2-h-1。

In this study, the metallic glass consisting of zirconium, copper, aluminum and nickel was selected as the photo-thermal conversion material. The filter paper substrate was the water carrier, and the fp1, fp3, and fp5 samples coated with metallic glass are prepared with different RF magnetron sputtering times (1, 3, and 5 hours). Samples were used as floating solar water evaporation systems for seawater desalination. The fp1, fp3, and fp5 samples could float on the water. The three samples still maintain an open pore structure, which can be used as a floating solar energy water evaporation system.
The XPS full spectra and depth profiling spectra could explore the metallic glass composition at different depths. Capillary flow analyzer could analyze the pore size distribution. Water contact angle could show the surface wettability. UV-Vis/NIR Spectrometer could evaluate the optical properties. Tensile test could evaluate mechanical strength. The effects of sputtering time on the pore size distribution of porous channels, surface wettability, solar absorptance, durability, chemical composition at different depths are also discussed.
Under the condition of 20-22°C temperature and 60-65% relative humidity, the experimental results of solar water evaporation efficiency show that both the evaporation rate and the photo-thermal conversion efficiency increase with the sputtering time (fp5> fp3> fp1> fp0). Under xenon lamp irradiation, deionized water with fp5 had the evaporation rate of 849 g-m-2-h-1, and its photo-thermal conversion efficiency could reach 66%. Under xenon lamp irradiation, deionized water with fp5 had the evaporation rate of 685 g-m-2-h-1, and its photo-thermal conversion efficiency could reach 53%. In addition, under different environments, the simulated seawater evaporation test was conducted with a handmade solar evaporator, and the water harvesting rate of the simulated seawater was discussed. Under indoor xenon lamp irradiation and outdoor sunlight irradiation, the water harvesting rate of fp5 could reach 414 g-m-2-h-1 and 593 g-m-2-h-1 respectively.
