Tuning the glass transition of siloxane-based poly(ionic liquid)s towards high ion conductivity Yuan, Jiayin Anton, Arthur Markus Attribution 4.0 International Chang, Jian 2021-07-15 Herein, we report a simple and versatile synthetic approach towards siloxane-based poly(ionic liquid)s (PILs) with unusually low glass transition temperatures (T<sub>g</sub>) down to −73°C, and thus “liquid-like” behavior at room temperature. We designed a polydimethylsiloxane-derived copolymer carrying dialkylimidazolium moieties, and by careful selection of the side-chain length and the type of anions we were able to manipulate its T<sub>g</sub> over a wide range and reach high ionic conductivities (σ<sub>DC</sub>) up to 4.8 × 10<sup>−5 </sup>S/cm at 300 K. The ionized species make up only a minor fraction (<25 mol%) of the overall repeating units and are supposedly randomly distributed: Yet our results indicate dramatic effects on the thermal properties due to repulsive interactions between ionic and non-ionic segments.
