Carbon-based membranes have been widely examined for their application to gas separation for their excellent mechanical properties and chemical stability. Previous studies have mainly focused on two-dimensional graphene derivatives such as graphene oxide. However, the graphene oxide-based membranes suffer from low permeability and stability in humid conditions by its hydrophilicity. Graphene oxide nanoribbon (GONR), a one-dimensional narrow strip of graphene with abundant nanopores and entangled structure, has drawn attention as a building block of gas separation membrane for its high permeability and stability in humid conditions. Herein, we demonstrate the polymer/GONR hybrid gas separation membrane prepared by a scalable shear coating method. The polymers were intercalated into GONR layers by simple mixing of solutions, and their interactions with CO2 enabled H2/CO2 separation. |
