离子化合物导电水凝胶在软智能设备的开发方面具有巨大的潜力。这些设备通常需要介电围巾来防止短路，从而导致设备的拉伸性低于水凝胶。从此以后，常用的介电材料，例如PDMS和Ecoflex，就不能被大幅度拉伸。需要具有超拉伸性的水凝胶装置来适应恶劣的应用环境。在此，我们提出了一种涂有介电层的水凝胶纤维，可以拉伸至其初始长度的 2000% 以上。当拉伸至约 1300% 时，纤维仍保持导电性。此外，核/鞘水凝胶纤维可以赋予多种功能特性，如电致发光（EL）、光致发光（PL）和磁响应性，证明了所得纤维的可扩展性。目前的工作可以为智能纺织品和可穿戴电子产品等众多下一代软设备铺平道路。 © 2019 Wiley periodicals, Inc.

Conductive hydrogels with ionic compounds possess great potential for the development of soft smart devices. A dielectric scarfskin is typically required for these devices to prevent short circuiting, leading to devices with lower stretchability than the hydrogel. Henceforth, commonly used dielectric materials, such as PDMS and Ecoflex, cannot be largely stretched. Hydrogel devices with ultrastretchability are required to accommodate hostile application environments. Herein, we propose a hydrogel fiber coated with a dielectric layer that can be stretched to over 2000% of its initial length. The fiber remains conductive when stretched to ~1300%. In addition, the core/sheath hydrogel fiber can be endowed with a variety of functional properties, such as electroluminescence (EL), photoluminescence (PL), and magnetic‐responsiveness, demonstrating scalability of the resultant fiber. The present work can pave the way for numerous next‐generation soft devices, such as smart textiles and wearable electronics. © 2019 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.
