Interfacial microfluidic processing of metal-organic framework hollow fiber membranes

Abstract

High-surface-area gas separation membranes Membranes for gas separation require a combination of high surface area and selective transport pathways. Brown et al. present a potentially scalable route for making high-quality gas separation membranes in a high-surface-area configuration. Using two different solvents flowing in opposite directions, a metal-organic framework material was selectively deposited within hollow polymer fibers. The membranes showed high-performance separation capabilities when tested with mixtures of hydrocarbon gases. Science , this issue p. 72
