AI Technical Summary
Existing ion-conductive fibers have shortcomings in terms of environmental adaptability, stability, conductivity and mechanical properties. In particular, their performance is unstable in high-temperature dry or low-temperature humidity environments, and ionic liquids are prone to leakage, making it difficult to balance conductivity and flexibility.
The dual confinement structure utilizes the continuous multi-level channels of fibrous porous material and the encapsulation layer to dual confine the ion-conducting medium, forming an integrated coaxial structure. The inner fibrous porous material provides a stable channel structure and mechanical support, while the outer encapsulation layer provides physical protection.
Maintaining stable flexibility and high ionic conductivity over a wide temperature range prevents ionic liquid leakage, improving fiber durability and lifespan, making it suitable for wearable devices and sensors in complex environments.
