Abstract
A hybrid crosslinked polymeric membrane and a process for fabricating the same are provided. Specifically, the hybrid crosslinked polymer membrane comprises a glassy polymer and a ladder-structured polysilsesquioxane and has a crosslinked structure. The hybrid crosslinked polymer membrane can have an excellent permeability of carbon dioxide by virtue of an increase in the free volume and enhanced plasticization resistance, chemical resistance, and durability.
Claims10
A hybrid crosslinked polymer membrane, which is prepared from a polymer composition comprising 70 to 90% by weight of a glassy polymer having a first functional group and 10 to 30% by weight of a ladder-structured polysilsesquioxane having a second functional group capable of reacting with the first functional group and has a crosslinked structure formed by a reaction of the first functional group and the second functional group,
- wherein the glassy polymer is a polyimide obtained by polycondensation of an aromatic carboxylic dianhydride and an aromatic diamine,
- the first functional group is a carboxyl group,
- the second functional group is an amine group, and
- 70 to 100% of each of the first functional group and the second functional group participates in the crosslinking reaction.
