Highly CO2-Permeable and Selective Polymer Nanocomposite Membranes

As technologies turn to more efficient routes to remove CO2 from mixed gas streams for H2 or air purification, new cost‐effective multifunctional materials are needed for the separation processes. Here, hybrid poly(ethylene glycol)/fumed silica nanocomposite membranes exhibiting high CO2/H2 selectiv...

Description
Summary:As technologies turn to more efficient routes to remove CO2 from mixed gas streams for H2 or air purification, new cost‐effective multifunctional materials are needed for the separation processes. Here, hybrid poly(ethylene glycol)/fumed silica nanocomposite membranes exhibiting high CO2/H2 selectivity (> 11) and CO2 permeability (∼ 83 Barrer), as well as robust mechanical properties and optical clarity, are reported (see Figure).
