Abstract: An ultra-thin anion exchange membrane incorporates functional additives to provide improved water management. Without the functional additives the ultra-thin membrane may have high cross-over and not be effective for many applications. A composite anion exchange membrane includes a porous scaffold support such as a porous polymer. The anion exchange polymer may be coupled to the porous scaffold, such as by being imbibed into the pores of the porous scaffold. The functional additives may contribute to increase water production, water retention, back-diffusion and reduce the gas crossover. A functional additive may include a reactive species, including a catalyst that reacts with oxygen or hydrogen, a plasticizer, a hygroscopic material and/or a radical scavenger.

Abstract: A container for treating a fluid with an ion-exchange system is provided. The container includes a housing extending in an upright position between a bottom port and an opposed top port. The housing has an internal chamber. A bottom plate is disposed in the internal chamber above the bottom port and having a plurality of openings defined therethrough. The bottom plate divides the internal chamber between a main chamber and a bottom chamber. The bottom chamber is defined between the bottom plate and the bottom port. A plurality of diffusers extend from the bottom plate into the main chamber. Each one of the plurality of diffusers has a diffuser tube section projecting upwardly from the bottom plate and in fluid flow communication with the bottom chamber. The diffuser tube section has radial openings circumferentially distributed along a length thereof to radially discharge the fluid in the main chamber.

Abstract: The present disclosure herein relates to a terminally-crosslinked methyl morpholinium-functionalized block copolymer, and an anion exchange membrane using the same, and more particularly, to a terminally-crosslinked block copolymer which has a novel structure, and in which, in a poly(arylene ether sulfone) multiblock copolymer (MM-PES) having methyl morpholinium as a conducting group, an azide compound may be used as a crosslinking agent so that crosslinking only occurs at ends of the polymer chains (xMM-PES), thereby minimizing conductivity loss, significantly increasing mechanical and chemical stability, attaining additional conductivity resulting from the three-dimensional structure of morpholinium, and reducing water uptake while enhancing water retention capacity, uses thereof as an alkaline fuel cell anion exchange membrane (AEM), and a method for conveniently preparing the same through simple heat-treatment.

Abstract: A polysulfone membrane is modified so that monomers are grafted onto the surface of the membrane. The polysulfone membranes can be grafted by contacting the membrane with a grafting solution and exposing the membrane to electromagnetic radiation, typically within the ultraviolet portion of the spectrum. The monomers that are grafted are typically anionic or cationic. The grafted membranes can be used for filtering impurities, such as positively and negatively charged particles, from a liquid. Anionic membranes provide improved filtration of negatively charged impurities, while cationic membranes provide improved filtration of positively charged impurities.

Abstract: Multipart functionalized materials are shown that remove sulfites from beverages and in particular wine. The functionalized materials consist of a solid support material having the ability to link polycarbonyls or polyamines thereto. The polycarbonyls and polyamines remove free and bound sulfites when put in contact with the beverage. The polycarbonyl and polyamine functionalized materials can be used separately or mixed together for accomplishing sulfite removal.

Abstract: Provided herein are compositions, CO2-permeable/selective membranes and related methods of making and using the membranes. Ionically cross-linked poly(ether)-based membranes were prepared for applications relating to CO2. These films were studied for their thermal curing behavior using DSC. The resulting free-standing membranes have Tgs near −64° C., TdS up to 230° C., and Young's modulus up to 4.2 MPa. These membranes showed CO2 permeabilities of 84-110 Barrer and CO2/N2 selectivity of 20-40.
