摘要： An anion exchange membrane is made by mixing 2 trifluoroMethyl Ketone [nominal] (1.12 g, 4.53 mmol), 1 BiPhenyl (0.70 g, 4.53 mmol), methylene chloride (3.0 mL), trifluoromethanesulfonic acid (TFSA) (3.0 mL) to produce a pre-polymer. The pre-polymer is then functionalized to produce an anion exchange polymer. The pre-polymer may be functionalized with trimethylamamine in solution with water. The pre-polymer may be imbibed into a porous scaffold material, such as expanded polytetrafluoroethylene to produce a composite anion exchange membrane.

摘要： A method for producing an ion-exchange resin having a water content of 5% by weight or less, a method for producing a lithography coating film forming-composition using the ion-exchange resin, and a method for washing the ion-exchange resin. The methods include the step of passing an organic solvent having a water content of 150 ppm or less through an ion-exchange resin precursor having a water content of 40% by weight or more, where a dehydration efficiency defined by the following equation is 5 or more: Dehydration efficiency=Dehydration rate (%)/[Weight of the organic solvent used per unit weight of the ion-exchange resin precursor (kg/kg)×Washing time (h)].

摘要： Provided are an anion exchange resin being capable of producing an electrolyte membrane, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer, which have improved electrical properties and chemical properties. For example, used is an anion exchange resin which has a hydrophobic unit being composed of bisphenol AF residues repeated via carbon-carbon bond and a hydrophilic unit being composed of hydrophilic groups repeated via carbon-carbon bond, in which the hydrophilic group is formed by connecting an anion exchange group to a fluorene backbone via a divalent saturated hydrocarbon group, and in which the hydrophobic unit and the hydrophilic unit are connected via carbon-carbon bond.

摘要： Embodiments described herein relate to compositions including iptycene-based structures. Some embodiments provide compositions including polymers having a backbone comprising an iptycene-based compound. Some embodiments described herein provide compositions having enhanced properties such as enhanced porosity, increased glass transition temperatures, and/or improved solubility as compared to traditional poly(aryl ether)-based compounds or traditional iptycene-based compounds. In some cases, the compositions may include various aryl ether compounds such as an aryl ether ketone incorporated into the polymer backbone. Non-limiting examples of suitable aryl ether compounds include polyaylethersulfones, polyaryletherketones, polyetherimides, and polyphenylene ethers. The compositions described herein may be useful in a wide variety of applications, including structural materials, flexible composites, ion conductors, fuel cell membranes such as proton exchanging membranes, sensors, preconcentrators, absorbents, or the like.
