| dc.description.abstract | 在本研究中，利用旋轉塗布在純銅表面鍍上二氧化鈦薄膜並使用紫外光源照射表面引起表面濕潤性的變化。利用X射線光電子能譜分析二氧化鈦薄膜表面化態與使用掃描電子顯微鏡分析二氧化鈦薄膜表面結構。當二氧化鈦表面在受到紫外光照射後，表面濕潤性會從疏水表面轉變為親水表面。疏水表面會利於氣泡成核提升熱傳係數；親水表面延緩薄膜沸騰的發生進而達到更高的臨界熱通量。在本研究中觀察到紫外光照射時機也會影響沸騰表現，實驗結果得出最佳的紫外光照射時間點是在分離氣泡狀態，利用高速攝影機拍攝氣泡動態，呈現出二氧化鈦表面在經過紫外光照射後棄泡動態變化。本實驗測試樣品S2經由紫外光照射臨界熱通量提升72%，熱傳係數提升49%相對於純銅表面∘ | zh_TW |
