Various embodiments demonstrate that an in-situ polymerization enables deposition of a homogeneous polyaniline layer with a controlled thickness on top of a porous polypropylene support. Photografting and subsequent modification with diamines affords composite membranes featuring both high permeability and selectivity that are well suited for applications such as separation of carbon dioxide from a natural gas.
