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. 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.
Claims25
A method for producing a gas separation article, said gas separation article comprising:
- a gas separation membrane,
- a 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,
- 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) 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,
- d) fixating the matrix material so as to fixate the particle groups thereby forming a gas separation membrane.
