A novel class of gas separation membrane based on organic ionic plastic crystals†
Abstract
The first use of organic ionic plastic crystals (OIPCs) as CO2 separation membranes is reported. The novel OIPC/PVDF nanofiber composites show CO2/N2 ideal selectivities of 30 at 35 °C. The dependence of gas permeability on the thermal phase of the plastic crystals is discussed.
