CO2 Capture Membrane

Caption

Freestanding and mechanically strong nanomembranes composed of two polymeric layers demonstrated superior carbon dioxide separation from nitrogen. As revealed by the study the surface of the composite membrane played a crucial role to achieve the CO2 selectivity. The interface layer composed of the interpenetrated gutter layer (PDMS) and ultrathin selective layer (Pebax-1657) polymers was conveniently controlled by oxygen plasma treatment of PDMS. The discovery provides new insights on the materials performance in the region of nanoscale thicknesses.
