Abstract
The Invention discloses a preparation method for a triptyl polymer separation membrane, wherein, it comprises the following steps: take triptycene compound containing active group, dichloride compound and diamino compound containing ether bond as monomers, and conduct polymerization in aprotic organic solvent in the presence of acid-binding agent; pour the obtained polymer solution into deionized water for precipitation after the reaction, filter out precipitates and wash with methanol and dry to get triptyl polymer; dissolve the triptyl polymer in aprotic organic solvent to produce a membrane-casting solution, apply the solution on support and dry to get a triptyl polymer separation membrane. The Invention solves the problem that the reticular polymer material is insoluble, and breaks the restriction for application of such material in separation membrane due to its insoluble and aging features.
