title = "Designing ultrathin film composite membranes: Importance of a gutter layer",
abstract = "The performance of composite membranes that utilize an ultra- Thin selective layer (<100 nm) can be improved with the introduction of an intermediate gutter layer (<100 nm) positioned between the selective layer and porous support. the properties of the gutter layer can be carefully chosen to enhance overall membrane performance, i.e., high permeance and high selectivity. however, the experimental determination of optimum gutter layer properties is very challenging, if not impossible, and modeling is needed to guide the selection process. in this presentation we address this need using a computational model to determine the effects of the gutter layer thickness and permeability on membrane performance. we show that a layer thickness of 1-2 times of the pore radius of the porous support yields the maximum improvement in permeance without significantly decreasing selectivity.",
