    • 研究主題
      • 天然氣水合物的理論模型建立與實驗量測
        天然氣水合物是全世界儲存量最大的含碳燃料,然而為進行天然氣水合物的開採以及後續儲存及運送,皆必須先得知天然氣水合物系統的熱力學與動力學性質。研究主要在於天然氣水合物相平衡理論模型的建立與實驗量測,並致力於以二氧化碳置換水合物中甲烷的開採技術研究。
      • 微奈米級結構表面上之濕潤現象
        我們致力於微奈米級圖案與超疏水表面製備,同時運用數值模擬與實驗探討液滴在微奈米級結構表面上之濕潤現象與蒸發行為,藉以改善相關應用,如:噴墨印刷、微流體……。
      • 含高分子與界面活性劑水溶液的物理化學行為
        含有高分子與界面活性劑系統的物性在許多實際應用,如:清潔劑、食物添加劑、化妝品、油漆、殺蟲劑與藥劑配方,扮演舉足輕重的角色。我們運用多種實驗技術來辨識與探討該系統的微結構與高分子/界面活性劑聚集行為。
