POLYMER COMPOSITE MEMBRANE FOR OLEFIN SEPARATION CONTAINING GRAPHENE AND FACILITATED OLEFIN TRANSPORTING MEMBRANE CONTAINING USING THE SAME

摘要

The present invention relates to a polymer composite thin-film used to separate olefins including graphene and a olefins transfer accelerating membrane using the same. According to the present invention, the membrane for separating the olefins including the graphene has increased permeability compared to a polymer membrane including a carbon-based material such as the carbon black instead of graphne and a membrane including metal nanoparticles without the graphene to selectively accelerate the transfer of the olefins. The present invention also has selection rate characteristics enabling the commercial application and the significantly increased permeability to eliminate the conventional distillation process.
