“…The diffraction pattern of PU investigated by XRD showed a broad diffraction peak at 2θ ≈19.5°, indicating the amorphous structure of PU (Figure S3). With the increase of LiTFSI content, the intensity of corresponding peak became weaker, demonstrating that the interruption effect of LiTFSI on the crystallization of PU gradually became stronger and the amorphous fraction of PU was more prominent [2a,28] . SAXS test was performed to further investigate the microstructure of PU.…”

Solid‐state ionic conductive elastomers (ICEs) can fundamentally overcome the disadvantages of hydrogels and ionogels (their liquid components tend to leak or evaporate), and are considered to be ideal materials for flexible ionic sensors. In this study, a liquid‐free ionic polyurethane (PU) type conductive elastomer (ICE‐2) was synthesized and studied. The polyurethane (PU) type matrix with microphase separation endowed ICE‐2 with excellent mechanical versatility. The disulfide bond exchange reaction in the hard phase and intermolecular hydrogen bonds contributed to damage repairing ability. ICE‐2 exhibited good ionic conductivity (2.86 × 10‐6 S/cm), high transparency (average transmittance > 89%, 400~800 nm), excellent mechanical properties (tensile strength of 3.06 MPa, elongation at break of 1760%, and fracture energy of 14.98 kJ/m2), appreciable self‐healing ability (healing efficiency > 90%), satisfactory environmental stability, and outstanding recyclability. The sensor constructed by ICE‐2 could not only realize the perception of temperature changes, but also accurately and sensitively detect various human activities, including joint movements and micro‐expression changes. This study provides a simple and effective strategy for the development of flexible and soft ionic conductors for sensors and human‐machine interfaces.

Comprehensive Summary With the rapid growth of soft electronic and ionotronic devices such as artificial tissues, soft luminescent devices, soft robotics, and human‐machine interfaces, there is a demanding need to accelerate the development of soft ionic conductive materials. To date, the first‐generation ionotronic devices are mainly based on hydrogels or ionogels. However, due to their intrinsic drawbacks, such as freezing or volatilization at extreme temperatures, and the leakage problem under external mechanical forces, the reliability of ionotronic devices under harsh conditions remains a great challenge. The advent of liquid‐free ionic conductive elastomers (ICEs) has the potentials to solve the issues related to the gel‐type soft conductive materials. The free ions shuttling within the ion‐dissolvable polymer network enable liquid‐free ICEs to exhibit unparalleled ionic conductivity and elasticity. Moreover, by tuning the composition and structure of the polymeric network, it is also feasible to integrate other desirable properties, such as self‐healing ability, transparency, biocompatibility, and stimulus responsiveness, into liquid‐free ICE materials. In this review, we summarize the design strategies of recently reported liquid‐free ICEs, and further explore the methods to introduce multifunctionality, which originate from the rational molecular design and/or the synergy with other materials. Moreover, we highlight the representative applications of liquid‐free ICEs in soft ionotronics. It is believed that liquid‐free ICEs might provide a unique material platform for the next‐generation ionotronics.
