摘要
The present invention relates to a polymeric hollow fiber membrane and a carbon molecular sieve hollow fiber membrane, both of which have excellent gas separation performance, and processes for preparing the same. Specifically, the present invention relates to a hybrid polymeric hollow fiber membrane that comprises a glassy polymer containing fluorine and a ladder-structured polysilsesquioxane, a hybrid carbon molecular sieve hollow fiber membrane prepared by pyrolysis thereof, and processes for preparing the same. The hybrid polymeric hollow fiber membrane and the hybrid carbon molecular sieve hollow fiber membrane according to the embodiments of the present invention are excellent in gas flux and selectivity and can have a large surface area per unit volume. Thus, they can be advantageously used for separating gases with a high energy efficiency on a large scale.
