Abstract

A high-performance CO2 separation membrane consisting of an ion gel has been prepared. The tetra-armed poly(ethylene glycol) ion gel contains a large fraction of ionic liquid (94 wt %) and shows excellent CO2 permselectivity over a wide temperature range, up to 100 °C. We also demonstrate that the ion gel can absorb CO2 without solvent seeping at a high pressure of 3 MPa.
