Highly Selective Multilayer Polymer Thin Films for CO2/N2 Separation Academic Article uri icon

abstract

  • ABSTRACTMultilayer thin films of poly(ethylene oxide) (PEO) and poly(methacrylic acid) (PMAA), deposited via layerbylayer (LbL) assembly from aqueous solutions, are investigated for CO2/N2 separation. Eight and ten bilayer (217 and 389 nm thick, respectively) PEO/PMAA thin films deposited on a 25 m polystyrene substrate exhibit CO2/N2 selectivities of 142 and 136, respectively. These are the highest reported todate for this gas pair separation using a homogeneous polymer film. While further work remains to improve CO2 permeability, these results indicate the potential of LbL assemblies as standalone CO2 separation membranes for lowflux/highpurity applications, or as part of a composite and/or mixedmatrix membrane for highflux applications. 2017 Wiley Periodicals, Inc.
