The present invention relates to the technical field of photoelectric materials, and in particular, to an alcohol dispersion of a conductive polyethylenedioxythiophene, and a method for preparing same and use of same. The present invention comprises a conductive polyethylenedioxythiophene and an alcohol, and the conductive polyethylenedioxythiophene comprises a polyethylenedioxythiophene cation and a fluorinated sulfonic acid ionomer counter anion. The present invention prepares a PEDOT alcohol dispersion by using an alcohol-dispersible highly fluorinated sulfonic acid ionomer as a counter anion to replace PSS, solving the hygroscopicity problem in conventional aqueous dispersions, and solving the problem that a conventional conductive aqueous dispersion of polyethylenedioxythiophene cannot be evenly applied on a hydrophobic surface due to high surface tension. The present invention has a simple synthesis process and is applicable to different substrates and different types of optoelectronic devices, thermoelectric devices, electrochromic thin films, and antistatic coatings, thus having broad prospects.

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.
