We propose elastic temperature-sensitive ion gels that visually inform thermal status by changing transmittance. For obtaining thermoresponsive gels, we synthesized a random copolymer of poly(styrene-ran-benzyl methacrylate-ran-methyl methacrylate) (P(S-r-BzMA-r-MMA)) that was carefully designed to include thermosensitive features and elasticity when mixed with ionic liquids. By adjusting the composition of gel systems, the detectable temperature range and mechanical robustness was tunable. The thermo-sensitivity of the gels was investigated in terms of transmittance, dynamics and reversibility. In addition, temperature dependent behaviors of the gels were analyzed by small-angle x-ray scattering (SAXS) measurements. Finally, we demonstrate temperature sensing applications of the thermoresponsive gels. |
