交联型聚乙二醇型聚酰胺胺S(PAMAM)在H2中表现出优异的CO2分离性能。然而，在实际应用中，应该增加二氧化碳的渗透率。利用聚乙烯醇(PVA)与一乙醇胺(MEA)的混合溶剂浇铸法制备了聚乙烯醇(PVA)基质，并将一乙醇胺(MEA)作为CO2捕集技术的示范性试剂。得到的聚合物膜可以自立，厚度大于3μm，胺含量小于80wt%。在40°C和80%相对湿度下测试了其气体渗透性能。随着聚合物膜中胺含量的增加，CO2的分离性能也随之提高。当胺含量为80wt%时，膜的CO2渗透系数为604barrer，CO2对H2的选择性为58.5，远高于相同操作条件下的PAMAM膜(分别为83.7barrer和51.8)。另一方面，乙胺(EA)也被引入到PVA基质中形成了一层薄膜。然而，所得到的聚合物膜具有轻微的二氧化碳选择性气体渗透性能。MEA中的羟基是高分离CO2性能的关键。
Poly(amidoamine)s (PAMAMs) incorporated into a cross-linked poly(ethylene glycol) exhibited excellent CO2 separation properties over H2. However, the CO2 permeability should be increased for practical applications. Monoethanolamine (MEA) used as a CO2 determining agent in the current CO2 capture technology at demonstration scale was readily immobilized in poly(vinyl alcohol) (PVA) matrix by solvent casting of aqueous mixture of PVA and the amine. The resulting polymeric membranes can be self-standing with the thickness above 3 μm and the amine fraction less than 80 wt%. The gas permeation properties were examined at 40 °C and under 80% relative humidity. The CO2 separation performance increased with increase of the amine content in the polymeric membranes. When the amine fraction was 80 wt%, the CO2 permeability coefficient of MEA containing membrane was 604 barrer with CO2 selectivity of 58.5 over H2, which was much higher than the PAMAM membrane (83.7 barrer and 51.8, respectively) under the same operation conditions. On the other hand, ethylamine (EA) was also incorporated into PVA matrix to form a thin membrane. However, the resulting polymeric membranes exhibited slight CO2-selective gas permeation properties. The hydroxyl group of MEA was crucial for high CO2 separation performance.
