Abstract:Although thin-film composite membranes have achieved great success in CO 2 separation, further improvements in the CO 2 permeance are required to reduce the size and cost of the CO 2 separation process. Herein, we report the fabrication of composite membranes with high CO 2 permeability using a laser-patterned porous membrane as the support membrane. High-aspect-ratio micropatterns with well-defined micropores on their surface were carved on microporous polymer supports by a direct laser writing process using … Show more
