Abstract

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