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.

A coating composition comprises a functionalized epoxy resin and a fluoroalkyl-modified particle, such as activated carbon or silica. The functionalized epoxy resin is a ternary polymer composition comprising one or more epoxy resin moieties linked to a polyethylene backbone through an oxygen atom, fluoroalkyl(poly)propionyl groups being grafted to the polyethylene backbone. The coating compositions have superhydrophobic properties useful for self-cleaning surfaces and bubble release from sensors.
