Multifunctional flexible sensors are the development
trend of wearable electronic devices in the future. As the core of
flexible sensors, the key is to construct a stable multifunctional
integrated conductive elastomer. Here, ionic conductive elastomers
(ICEs) with self-wrinkling microstructures are designed and
prepared by in situ phase separation induced by a one-step
polymerization reaction. The ICEs are composed of ionic liquids as
ionic conductors doped into liquid crystal elastomers. The doped
ionic liquids cluster into small droplets and in situ induce the
formation of wrinkle structures on the upper surface of the films.
The prepared ICEs exhibit mechanochromism, conductivity, large
tensile strain, low hysteresis, high cycle stability, and sensitivity
during the tension-release process, which achieve dual-mode
outputs of optical and electrical signals for information transmission and sensors.
