Abstract:
Fiber‐shaped conductors with high electrical conductivity, stretchability, and durability have attracted increasing attention due to their potential for integration into arbitrary wearable forms. However, these fiber conductors still suffer from low reliability and short life span, particularly in harsh environments. Herein, a conductive, environment‐tolerant, stretchable, and healable fiber conductor (CESH), which consists of a self‐healable and stretchable organohydrogel fiber core, a conductive and buckled silver nanowire coating, and a self‐healable and waterproof protective sheath, is reported. Such a multilayer core–sheath design not only offers high stretchability (≈2400%), high electrical conductivity (1.0 × 10 6 S m −1 ), outstanding self‐healing ability and durability, but also possesses unprecedented tolerance in harsh environments including wide working temperature (−60–20 °C), arid (≈10 % RH (RH: room humidity)), and underwater conditions. As proof‐of‐concept demonstrations, CESHs are integrated into various wearable formats as interconnectors to steadily perform the electric function under different mechanical deformations and harsh conditions. Such a new type of multifunctional fiber conductors can bridge the gap in stretchable and self‐healing fiber technologies by providing ultrastable electrical conductance and excellent environmental tolerance, which can greatly expand the range of applications for fiber conductors.
