Abstract: The present disclosure provides a method for producing a gas separation article, said gas separation article comprising: a gas separation membrane, optionally a support, and optionally an additional support, said method comprising the steps of: a) providing a matrix, said matrix having a viscosity from 1 centipoise to 40000 centipoise, said matrix comprising or consisting of one or more monomers, oligomers and/or polymers, and optionally a solvent, b) contacting the matrix of step a) with a support comprising at least one side, said at least one side facing said matrix, thereby forming (i) a matrix side contacting the support and (ii) a matrix side opposite the side contacting the support, c) optionally contacting the matrix side opposite the side contacting the support with an additional support, d) subjecting said matrix contacted with said support to one or more electric fields that is/are substantially parallel to a plane in which the support extends, or substantially perpendicular to a plane in which the support extends e) fixating the one or more monomers, oligomers and/or polymers of the matrix subjected to one or more electric fields in step d) thereby forming a solid gas separation membrane, and f) optionally removing the support and/or the additional support. The present disclosure also gas separation article obtainable by the aforementioned method as well as use of said gas separation article for separation of gases in a gas mixture.

Abstract: The disclosure provides a method for producing a gas separation article, said gas separation article comprising: a gas separation membrane, optionally a support, and optionally an additional support said method comprising the steps of: a) providing a matrix comprising: a matrix material having a viscosity from 1 cP to 40000 cP, particles, said particles being free from functionalized carbon nanotubes, and optionally a solvent, b) contacting the matrix of step a) with a support comprising at least one side, said at least one side facing said matrix, thereby forming (i) a matrix side in contact with the support and (ii) a matrix side opposite the side in contact with the support, c) optionally contacting the matrix side opposite the side contacting the support with an additional support, d) subjecting said matrix being in contact with said support to one or more electric fields whereby the particles form particle groups in a plurality of substantially parallel planes, said particle groups in each of said plurality of substantially parallel planes being aligned substantially parallel with the one or more electric fields, e) fixating the matrix material so as to fixate the particle groups thereby forming a gas separation membrane, and f) optionally removing the support and/or the additional support. The disclosure also provides a gas separation membrane obtainable by the aforementioned method as well as use thereof for separation of gases in a gas mixture.
