Abstract
We report the synthesis of a series of ionic polyurethanes (PUs) issued from the polyaddition of a 1,2,3-triazolium-functionalized diol monomer having a bis(trifluoromethylsulfonyl)imide counter-anion with four aliphatic, cycloaliphatic or aromatic commercial diisocyanates. The obtained polymers were characterized using 1H, 13C and 19F NMR spectroscopy, size exclusion chromatography (SEC), solubility, differential scanning calorimetry, thermogravimetric analysis, broadband dielectric spectroscopy, as well as CO2 uptake and permeability measurements. These new ionic PUs exhibit glass transition temperatures ranging from −25 to 28 °C, temperatures at 10% weight loss ranging from 307 to 320 °C, ionic conductivities at 30 °C under anhydrous conditions up to 10−6 S cm−1 and CO2 uptake of ca. 2.6 mg g−1 at 2 bars.
