本研究利用熱重分析儀量測聚醚醯亞胺(Poly(etherimide), PEI)之熱重損失,發現其熱穩定性優於聚醯亞胺(Polyimide, PI),故選擇其作為碳膜之前趨物;實驗中以SEM觀察到以滑動塗佈方法(Slide casting) 製備而成的碳膜之膜厚為高達28.25μm,進一步以光學顯微鏡觀察此碳膜表面結構,相較其他成膜程序之碳膜也較無缺陷,此外氫氣對於其他氣體的選擇率分別H2/CO2為5.4,H2/N2為20.2,H2/CH4為15.6,其氣體分選效果亦最為顯著;另外,實驗結果與Robenson這位學者所提出的Upper Bound line比較下,發現利用Slide casting在裂解溫度600℃條件下,H2/N2已達到Upper Bound line的氣體分離水準,此外H2/CH4的分選上更是優異於Robenson’s Upper Bound line。

Carbon membranes sieve (CMS), an inorganic membrane, has emerged as an alternative membrane technology in the field of gas separation. CMS have molecular sieving mechanism. They consist of micro pore channels with uniform pores to separate the different gas molecules in Angstroms. CMS is an attraction in characteristics such as excellent gas permeability, selectivity and thermal stability compared with the other molecular sieve materials. In this study, carbon membranes are prepared by pyrolysis of different polymers at higher temperatures. Preparation of carbon membranes consist several key parameters such as pyrolysis temperature, heating rate, phase inversion method and thickness. The characterization of CMS was carried out by thermal analysis, FTIR and SEM.
The results obtained from TGA analysis show Poly(etherimide) (PEI) has better thermal stability than Polyimide (PI). Therefore, PEI is taken as the major carbon source for CMS preparation. Membranes made by slide casting method have the thickness 28.25μm, and few cracking were noticed as compared with other preparation methods of CMS using optical microscope. Experimental results indicate that permeability and selectivity of slide casting membranes, measured at 25 ˚C, for PEI derived CMS are: permeability (H2) = 659 barrers, selectivity (H2/N2)=20.2 and (H2/CH4)=15.6. The correlation of the permeability versus perm selectivity for the PEI derived carbon membranes prepared in this study exhibited excellent performance as compared to the derived CMS membranes prepared at 600℃. In addition, the performance exceeded Robinson's upper bound line for conventional polymeric membranes.
