摘要： The present invention includes a hydrogel and a method of making a porous hydrogel by preparing an aqueous mixture of an uncrosslinked polymer and a crystallizable molecule; casting the mixture into a vessel; allowing the cast mixture to dry to form an amorphous hydrogel film; seeding the cast mixture with a seed crystal of the crystallizable molecule; growing the crystallizable molecule into a crystal structure within the uncrosslinked polymer; crosslinking the polymer around the crystal structure under conditions in which the crystal structure within the crosslinked polymer is maintained; and dissolving the crystals within the crosslinked polymer to form the porous hydrogel.

摘要： The invention described herein generally pertains to a composition that includes a silyl-terminated polymer having silyl groups linked to a polymer backbone via triazole. The silyl-terminated polymer is a reaction product of a functionalized polymer backbone and a functionalized silane. The polymer backbone includes a first functional group, which may be one of an azide or an alkyne. The functionalized silane includes a second functional group may also be one of an azide or an alkyne, but is also different from the first functional group. The functionalized polymer backbone is reacted with the functionalized silane in the presence of a metal catalyst.

摘要： Methods of preparing reinforced anion exchange membranes are provided, as well as produced membranes and corresponding devices utilizing the membranes. Methods comprise compounding a halide-functionalized polymer (selected to react with amines to yield anion-conducting quaternary amine groups) with thermoplastic polymer(s) (selected to support and/or reinforce the membrane), and with copolymer(s) (selected to enhance the compounding of the polymers)—by heating, mixing and cooling—to form blend pellets, extruding the blend pellets to form a blend film, cross-linking polymer(s), and functionalizing the blend film to prepare the anion exchange membrane. Functionalization comprises a quaternization step comprising reacting halogen groups of the first polymer with tertiary amines to produce the quaternary amine groups with ion-exchange functionality. Reinforced anion exchange membranes are provided, which are produced by the disclosed methods, functionalized to yield a membrane for fuel cell(s), electrolyzer(s), reversible electrochemical device(s), desalination unit(s), etc.

摘要： Disclosed are various polymer solid electrolyte materials suitable for various electrochemical devices and methods for making or using the same. The polymer solid electrolyte comprises a crosslinked polymer from a polymer. Certain embodiments are generally directed to solid electrolytes having relatively high ionic conductivity and/or other mechanical or electrical properties, e.g., tensile strength or decomposition potential. Certain aspects include a polymer, a plasticizer, and an electrolyte salt. In some cases, the polymer for synthesizing the crosslinked polymer may exhibit certain structures such as:




where R1 can be one of the following groups:





where n is an integer between 1 and 10000, m is an integer between 1 and 5000, and R2 to R6 are each independently selected from the group consisting of hydrogen, methyl, ethyl, phenyl, benzyl, acryl, epoxy ethyl, isocyanate, cyclic carbonate, lactone, lactam, and vinyl; and * indicates a point of attachment.
