Highly stretchable and transparent ionic conducting materials have enabled new concepts of electronic devices denoted as iontronics, with a distinguishable working mechanism and performances from the conventional electronics. However, the existing ionic conducting materials can hardly bear the humidity and temperature change of our daily life, which has greatly hindered the development and real-world application of iontronics. Herein, we design an ion gel possessing unique traits of hydrophobicity, humidity insensitivity, wide working temperature range (exceeding 100°C, and the range covered our daily life temperature), high conductivity (10~10 S/cm), extensive stretchability, and high transparency, which is among the best-performing ionic conductors ever developed for flexible iontronics. Several ion gel-based iontronics have been demonstrated, including large-deformation sensors, electroluminescent devices, and ionic cables, which can serve for a long time under harsh conditions. The designed material opens new potential for the real-world application progress of iontronics.
高拉伸性和透明的离子导电材料催生了被称为离子电子学的新型电子器件概念，其工作机制和性能与传统电子学截然不同。然而，现有的离子导电材料几乎无法承受我们日常生活中的湿度和温度变化，这极大地阻碍了离子电子学的发展和实际应用。在此，我们设计了一种离子凝胶，它具有疏水性、湿度不敏感性、宽工作温度范围（超过100°C，涵盖了我们日常生活的温度范围）、高电导率（10~10 S/cm）、广泛的拉伸性和高透明度等独特特性，是迄今为柔性离子电子学开发的性能最佳的离子导体之一。已经展示了几种基于离子凝胶的离子电子器件，包括大变形传感器、电致发光器件和离子电缆，它们可以在恶劣条件下长时间工作。所设计的材料为离子电子学的实际应用进展开辟了新的潜力。
