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. The present disclosure also provides a 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.
Claims22
A method for producing a gas separation article,
- said gas separation article comprising:
- a gas separation membrane, and
- a support
- said method comprising the steps of:
- a) providing a matrix,
- said matrix having a viscosity from 1 centipoise to 40000 centipoise,
- and said matrix comprising or consisting of one or more monomers, oligomers and/or polymers,
- b) contacting the matrix of step a) with the support, wherein the support comprises 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) 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
- d) 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.
