文摘

Polymer brushes functionalized double-shelled organic submicrocapsules are prepared. Organic submicrocapsules are used to fabricate mixed matrix membrane. CO2 transport passageways are widened due to the presence of polymer brushes. Permeability and selectivity of membranes are tested for CO2/CH4(N2) systems. Gas separation performance of MMMs surpasses Robeson upper bound revised in 2008.
