Abstract: A micro-electro-mechanical device includes an ion exchange polymer coated onto a surface or within pores of a micro-electro-mechanical portion. The micro-electro-mechanical device may be an electrode, a sensor or a cantilever. The ion exchange polymer may comprise an additive, such as an inorganic particle or powder or a metal-organic framework compound. Gases may react with the ionomer and create voltage and/or current which can be measured. The incorporation of ion exchange polymer with a MEM to produce electrode can provide interesting chemical, mechanical and electrical properties, which may have promise in sensor application and some other applications. The ion exchange polymer may be either cation exchange polymer or anion exchange polymer. The ion exchange polymer can be chemically cross-linked, or reinforced by support material or additive.

Abstract: An ion exchange membrane is provided which includes an ion exchange polymer that is partially cross-linked. The partially cross-linked ion exchange polymer will be more stable and will not be washed out over time. The ion exchange polymer may be UV or chemically cross-linked, wherein a cross-linking compound is added to the ion exchange polymer either before or after coupling to a support material. A support material may be made of, or be coated with, a cross-linking compound and the support material may initiate cross-linking proximal to the support material. The support material may be made of a material that chemically bonds with the ionomer.

Abstract: An electrochemical oxygen pump moves or pumps oxygen molecules with a unique anion conducting layer comprising an anion conducting polymer. These pumps can either be used as high precision oxygen flow meters or as oxygen filters. The system can be plumbed to have air as the inlet and the pump will selectively pump oxygen out, offering another way to remove oxygen from the air, along with distillation or pressure swing absorption.

Abstract: 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 trimethylamine 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.

Abstract: An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.
