In this work, we introduce highly thermo-mechanical durable ion gel and simple fabrication strategies for achieving highly thermo-mechanical durable MSCs. To achieve thermo-mechanical stable MSCs, we first tailored a molecular design of polymer gelator considering that thermo-mechanical properties of ILs-insoluble components strongly affect to those of ion gel. Based on this consideration, we proposed that copolymerization of ILs-insoluble components with high-glass transition temperature (Tg) and ILs-soluble poly(methyl methacrylate) (PMMA), and PMMA-ran-poly(methacrylic acid) (PMMA-r-PMAA) were synthesized. With high Tg of PMAA, the capability of MAA moiety to intermolecular hydrogen bonding contributes to the durability of ion gel.
