鋯金屬有機骨架及其缺陷衍生物對混合基質薄膜的氣體選擇性之影響研究
The Gas Selectivity of Mixed-Matrix Membranes with Zirconium Metal-Organic Frameworks and Defect Derivatives
摘要
本研究利用多種常見的UiO-66模組劑以及不同合成方式，調控缺陷程度以形成不同的孔洞型態，並進一步探討對二氧化碳吸附能力的影響，之後透過不乾燥方法 (Dry-free)對UiO-66進行處理並摻入聚醚嵌段醯胺 (polyether block amide, Pebax® MH 1657)中以合成混合基質薄膜 (mixed-matrix membranes, MMMs)。首先將MOF比例控制在5 wt%並與純Pebax膜相比，混合基質薄膜能得到比純Pebax膜更優秀的二氧化碳滲透率以及氣體選擇性，可以觀察到隨著UiO-66的缺陷程度提升，二氧化碳滲透通量最高可提升55 %；而選擇性也依不同的模組劑可提升約33 %。隨後將MOF的摻入量提升至10 wt%、20 wt%、30 wt%在進行氣體分離的測試，從結果得知在10 wt%的條件下達到最佳的CO2滲透率 (200 barrer)以及CO2/N2的氣體選擇性 (59.32)。

In this study, we use several types of Metal-Organic Frameworks (MOFs), called UiO-66, modulator and different synthesis process included hydrothermal method and reflux method to control the defect of UiO-66 to form different nanoporous MOFs and then find out the effect for CO2 adsorption. After that, we use the Polyether Block Amide (Pebax® MH 1657) as polymer to synthesis the Mixed-Matrix Membranes (MMMs) by using Drying-free method for reducing the interfacial effect between the MOF and Pebax. First, we load 5 wt% MOF to Pebax, and it enhance the gas permeability of CO2 by 55 % and gas selectivity of CO2/N2 by 33 % to neat Pebax membrane. Next, we increase the MOF loading amount from 5 wt% to 30 wt% and measure gas permeability again. In conclusion, we find that Pebax with 10 wt% UiO-66-LP has the best effect with both CO2 gas permeability (200 barrer) and CO2/N2 selectivity (59.32).
