摘要： This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.

摘要： The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2/N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2/N2 separation.
摘要翻译：本发明涉及交联膜，特别是交联聚（环氧乙烷） - 醋酸纤维素 - 倍半硅氧烷（PEO-CA-Si）有机 - 无机混合膜及其在气体分离中的应用。这些交联的PEO-CA-Si膜通过在形成膜期间在乙酸催化剂存在下通过可交联的PEO-有机三烷氧基硅烷和CA-有机三烷氧基硅烷聚合物的原位溶胶 - 凝胶共缩合制备。通过PEO（或CA）上的羟基与有机三烷氧基硅烷上的异氰酸酯之间的反应合成可交联PEO-和CA-有机三烷氧基硅烷聚合物，以在温和条件下形成氨基甲酸酯键。与CA膜相比，交联的PEO-CA-Si膜显示出增加的CO 2 / N 2选择性和CO 2渗透性，这表明这些膜对于气体分离如CO 2 / N 2分离是非常有希望的。

摘要： The present invention discloses mixed matrix membranes (MMMs) containing polymer-functionalized low acidity, ultra low silica-to-alumina ratio, nano-sized SAPO-34 small pore molecular sieves and a continuous polymer matrix and methods for making and using these membranes. The surface functionalization of these molecular sieves provides a desired interfacial adhesion between SAPO-34 nano-particles and the continuous polymer matrix, which results in either no macrovoids or voids of less than 5 angstroms at the interface of the continuous polymer matrix and SAPO-34 in the MMMs. These MMMs, in the form of symmetric dense film, asymmetric flat sheet membrane, or asymmetric hollow fiber membranes, have good flexibility and high mechanical strength, and exhibit remarkably enhanced CO2 permeability (or CO2 permeance) and maintained CO2/CH4 selectivity over the continuous polymer matrices for CO2/CH4 separation. The MMMs of the present invention are suitable for a variety of liquid, gas, and vapor.

摘要： This invention describes a new concept of flexible template-directed microporous partially pyrolyzed polymeric membranes which have greatly improved performance in separation of gas pairs compared to their precursor polymeric membranes. Organic hosts, such as crown ethers, cyclodextrins (CDs), calixarenes (CXs), and spherands, or polymeric additives, such as poly(ethylene glycol) (PEG) and polyvinylpyrrolidone (PVP) were used as the micropore-forming templates. Micropore-forming template/polymer blend membranes comprising organic micropore-forming templates embedded in a polymer matrix were prepared by dissolving the organic micropore-forming templates in the polymer solution followed by solution-casting and solvent evaporation or solvent exchange. Low-temperature selectively pyrolyzing micropore-forming templates in the micropore-forming template/polymer blend membranes at a nitrogen flow resulted in the formation of flexible microporous partially pyrolyzed polymeric membranes.
