In this work, a stretchable, dual thermo-responsive and strain-responsive
ionogel has been synthesized by one-step photopolymerization. The obtained ionogel shows
an ultrahigh stretchability (～3000%), a high ionic conductivity (up to 3.1 mS/cm), and a
good temperature tolerance (?40 to 300 °C). Importantly, these ionogels show an upper
critical solution temperature-type phase transition with a wide tunable phase-transition
temperature (17.5?42.5 °C) and reversible color/transparency switching. In particular, the
as-prepared ionogel-based flexible/wearable temperature monitors and smart windows show
an excellent designability and programmability, temperature modulation ability, and thermal
responsiveness. Moreover, the ionogels-based strain sensors have temperature- and straindual
responsibility and a broad strain-sensing range (1?700%), which can effectively
monitor various motions. This strategy of fabricating dual thermo- and strain-responsive
ionogels by using a one-step method and only one polymer holds great promise for the next
generation of multifunctional stimuli-responsive materials.
