Thin film formation via the Layer-by-Layer method is now a well-established and broadly used method in materials science. We have been keenly interested in exploiting this technique in the area of gas separations. Specifically, we have sought to create hyperthin (<100 nm) polyelectrolyte-based membranes that have practical potential for the separation of CO2 from N-2 (flue gas) and H-2 from CO2 (syngas). In this personal account, we summarize recent studies that have been aimed at measuring the influence of a variety of factors that can affect the permeability and permeation selectivity of hyperthin polyelectrolyte multilayers (PEMs).
