摘要：金屬有機骨架(Metal Organic Framework，MOF)為近五年來最熱門之結晶性微孔洞(孔徑<2 nm)材料，材料學界預期MOF將能廣泛應用於氣體吸附、氣體感測、氣體分離、催化、電化學等多項領域中。然而，現今MOF材料發展最大的瓶頸是多數團隊能合成出MOF的粉體，但無法將其製備成薄膜。而過去五年來MOF薄膜製備的相關研究遠遠不及MOF粉體性質研究之發展。由於多數元件應用必須要將材料製備成薄膜形式，而MOF薄膜之如此不對等之技術發展，大幅限制了MOF之應用性。本研究計畫期望建立將MOF薄膜塗佈於不同種類基材之關鍵技術。由固態薄膜性質檢測之結果，我們將探討懸MOF懸浮液特性、薄膜微結構、與薄膜固態性質(機械性質、介電常數、微觀結構)三者之關聯性。最終，我們將把MOF薄膜之氣體分離效能最佳化，並且將其製備成具有高選擇性之氣體感測元件。

Abstract: Metal Organic Frameworks (MOFs) are crystalline microporous materials, and have drawn an increasing research attention over the past five years. It is expected that MOFs can be broadly applied to gas adsorption, gas sensing, gas separation, catalysis, and electrochemistry. However, one of the grand challenges of MOF research is that MOFs can be easily synthesized in power form, but not thin film form. We summarize the MOF related paper and MOF thin film related paper over the past five years. However, most device applications require the thin film form, instead of the powder form, of MOF materials. The lack of a generalized method of MOF thin film fabrication strongly limits the applications of MOF materials. In this proposed work, we plan to develop the key techniques for the fabrication of MOF thin films on various substrates. We will investigate the gas diffusion through MOF thin films, and compare the experimental and simulated results. We will also measure the mechanical and electrical properties of MOFs. Finally, we will optimize the gas selectivity of MOF thin films for the gas sensing application.
