    • The present invention discloses new types of polybenzoxazole-based mixed matrix membranes and methods for making and using these membranes. The polybenzoxazole-based mixed matrix membranes are prepared by fabricating a polyimide-based mixed matrix membrane by dispersing molecular sieve particles in a continuous aromatic polyimide matrix with pendent hydroxyl groups ortho to the heterocyclic imide nitrogen; and then converting the polyimide-based mixed matrix membrane to a polybenzoxazole-based mixed matrix membrane by heating between 200 and 600C under inert atmosphere or vacuum. The polybenzoxazole-based mixed matrix membranes of the present invention can be fabricated into any convenient geometry such as flat sheet (or spiral wound), tube, hollow fiber, or thin film composite. These polybenzoxazole-based mixed matrix membranes exhibit high thermal stability, significantly higher selectivity than the neat polybenzoxazole polymer membranes, and much higher permeability than traditional mixed matrix membranes.
    • 本发明公开了新型的基于苯并恶唑的混合基质膜,以及制造和使用这些膜的方法。 基于聚苯并恶唑的混合基质膜通过将分子筛颗粒分散在具有与杂环酰亚胺氮原子相邻的侧羟基的连续芳族聚酰亚胺基体中制备聚酰亚胺基混合基质膜来制备; 然后通过在惰性气氛或真空下在200℃至600℃之间加热将聚酰亚胺基混合基质膜转变成聚苯并恶唑类混合基质膜。 本发明的基于聚苯并恶唑的混合基质膜可以制成任何方便的几何形状,例如平板(或螺旋缠绕),管,中空纤维或薄膜复合材料。 这些基于聚苯并恶唑的混合基质膜具有高的热稳定性,比纯聚苯并恶唑聚合物膜显着更高的选择性,并且比传统的混合基质膜具有更高的渗透性。

    • The present invention discloses fluoropolymer coated membranes and methods for making and using these membranes. The fluoropolymer coated membranes are prepared by coating a porous asymmetric membrane layer with a thin layer of fluoropolymer coating. The porous asymmetric membrane layer comprises an asymmetric cellulosic membrane, an asymmetric polymer membrane, or an asymmetric molecular sieve/polymer mixed matrix membrane with a low selectivity and high permeance. The fluoropolymer coating improves the selectivity of the porous asymmetric membrane layer and maintains the membrane performance with time. The fluoropolymer coated membranes are suitable for a variety of liquid, gas, and vapor separations such as desalination of water by reverse osmosis, non-aqueous liquid separation such as deep desulfurization of gasoline and diesel fuels, ethanol/water separations, pervaporation dehydration of aqueous/organic mixtures, CO2/CH4, CO2/N2, H2/CH4, O2/N2, olefin/paraffin, iso/normal paraffins separations, and other light gas mixture separations.
    • 本发明公开了含氟聚合物涂覆的膜和用于制造和使用这些膜的方法。 含氟聚合物涂覆的膜通过用含氟聚合物涂层的薄层涂覆多孔不对称膜层来制备。 多孔非对称膜层包含具有低选择性和高渗透性的不对称纤维素膜,不对称聚合物膜或不对称分子筛/聚合物混合基质膜。 含氟聚合物涂层改善了多孔不对称膜层的选择性并随时间维持膜性能。 含氟聚合物涂层膜适用于各种液体,气体和蒸汽分离,如通过反渗透脱盐水,非水液体分离如汽油和柴油燃料的深度脱硫,乙醇/水分离,水溶液的渗透汽化脱水 /有机混合物,CO 2 / CH 4,CO 2 / N 2,H 2 / CH 4,O 2 / N 2,烯烃/石蜡,异/正链烷烃分离和其他轻质气体混合物分离。

    • The present invention discloses a new type of high performance polymer membranes derived from aromatic polyimide membranes and methods for making and using these membranes. The polymer membranes described in the present invention were derived from aromatic polyimide membranes by crosslinking followed by thermal treating. The aromatic polyimide membranes were made from aromatic polyimide polymers comprising both pendent hydroxy functional groups ortho to the heterocyclic imide nitrogen and cross-linkable functional groups in the polymer backbone. The high performance polymer membranes showed significantly improved permeability for gas separations compared to the aromatic polyimide membranes without any treatment. The high performance polymer membranes also showed significantly improved selectivity for gas separations compared to the thermal-treated but non-UV-crosslinked aromatic polyimide membranes. The high performance polymer membranes of the present invention are suitable for liquid, gas, and vapor separations, as well as for catalysis and fuel cell applications.
    • 本发明公开了一种衍生自芳族聚酰亚胺膜的新型高性能聚合物膜以及制造和使用这些膜的方法。 本发明中描述的聚合物膜通过交联然后进行热处理从芳族聚酰亚胺膜得到。 芳族聚酰亚胺膜由芳族聚酰亚胺聚合物制成,其中包含杂环酰亚胺氮原子的邻接羟基官能团和聚合物主链中的可交联官能团。 与没有任何处理的芳族聚酰亚胺膜相比,高性能聚合物膜显示出显着改善气体分离的渗透性。 与热处理但非UV交联的芳族聚酰亚胺膜相比,高性能聚合物膜还显示出对气体分离的选择性显着提高。 本发明的高性能聚合物膜适用于液体,气体和蒸汽分离,以及催化和燃料电池应用。
