ANION-EXCHANGE MEMBRANES AND METHODS OF MAKING AND USING THE SAME
The invention relates to an anion-exchange membrane (AEM) having a multiblock copolymer including a hydrophilic norbornene-based monomer and a hydrophobic alkene-based or norbornene-based monomer.

Ultrasonic cavitation enabled tuning of persistent micelles
A method to quickly adjust the size of micelles and then return the micelles to a persistent state is provided. Specifically, the present invention is directed to a method for block copolymer micelle growth under high-χN solution conditions where ultrasonic cavitation facilitates rapid solution-gas interface production that accelerates micelle growth by an order of magnitude over other methods such as vortexing. The persistent micelles formed by the method of the present invention can then be used for controlled delivery of dispersions in organic electronic coatings, paint, or drug delivery applications and can also be used to control the pore size of films that include an oxide, a nitride, a carbide, a metal, or a carbon material.
METHOD OF MAKING COEXTRUDED CROSSLINKED POLYOLEFIN FOAM WITH POLYAMIDE CAP LAYERS
Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
THERMALLY STABLE HYDROCARBON-BASED ANION EXCHANGE MEMBRANE AND IONOMERS
An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.
