摘要： A polymeric hollow fiber membrane is provided having a crosslinked selective layer formed by sequentially performing coating of a polymer precursor on a crosslinked polymeric hollow fiber membrane support and thermal condensation and thermal crosslinking thereof, a carbon molecular sieve hollow fiber membrane, methods for producing the same, and methods of separating gases using the same. The polymeric hollow fiber membrane and the carbon molecular sieve hollow fiber membrane each have a thin crosslinked selective layer and excellent plasticization resistance and separation performance. Accordingly, the polymeric hollow fiber membrane and the carbon molecular sieve hollow fiber membrane, each of which has a thin crosslinked selective layer, can be effectively used in the separation of a mixed gas.

摘要： 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.

摘要： A polymer blend membrane includes a polyether-based copolymer and a polyether polymerized in situ and has high permeability and high selectivity for carbon dioxide. In the polymer blend membrane, the free volume of the polyether-based copolymer is greatly increased, and the adsorption capacity for carbon dioxide is enhanced. Thus, it can have excellent mechanical properties and excellent permeability and selectivity for carbon dioxide.

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.
