Abstract: A method is disclosed for the preparation (by the utilization of a proper solvent system) of dry asymmetric membranes comprising a porous layer of interconnected crystals of polymer material. Membranes of many polymer materials may be optionally prepared either with or without a dense surface layer as one face thereof. In either case the porous layer is structured with graded porosity. A three-component casting solution is prepared containing the polymer, a first good volatile solvent for the polymer and (relative to the first solvent) a poor less-volatile solvent for the polymer, which is miscible with the good solvent. A membrane is cast, allowed to desolvate for a short time and is then immersed in a leaching agent, that is miscible with both the aforementioned solvents but is a non-solvent for the polymer. The membrane is then permitted to dry.

Abstract: Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.

Abstract: The further advancement of membrane separation processes requires the development of more selective membranes. In this study, membranes that take inspiration from biological systems and use multiple functionalities of unique chemical design to control solute transport through chemical factors in addition to steric factors are detailed. Specifically, copolymer materials tailor-made for the generation of nanofilters that possess a high density of well-defined pores lined by azido moieties allowed for the generation of chemically-patterned mosaic membranes in a rapid manner through the use of printing devices. By engineering the composition of the reactive ink solutions used for chemical functionalization, large areas of patterned membranes were generated in seconds rather than hours. Charge mosaic membranes were used as an example of this novel platform.

Abstract: Composite materials including cellulose nanocrystals incorporated into a polymer aerogel scaffold, wherein the cellulose nanocrystals serve as a reinforcement agent to result in the formation of less dense aerogels, improve the tensile mechanical properties of aerogel films, and reduce aerogel shrinkage upon thermal exposure. After gelation, the gel is dried via a suitable method such as supercritical CO2 extraction, freeze drying or other method, to produce the CNC/polymer composite aerogel. Properties of the composite aerogel can be tailored via surface modification of the cellulose nanocrystals as well as through the backbone structure of the polymer.
