High-performance stretchable conductive fibers are desired for the development of electronic devices. Here we show a simple spinning method to prepare hydrogel with ordered polymer chain alignment that mimics hierarchically organized structure spider silk. The as-prepared sodium polyacrylate fiber is further coated thin layer polymethyl acrylate form core-shell water-resistant MAPAH fiber. Owing coexistence and reversible transformation crystalline amorphous domains in fibers, exhibit high tensile strength, large stretchability fast resilience from strain. can serve as highly wire core an insulating cover. conductivity retained at -35 °C, indicating its anti-freezing property. As prime example will shed light on design next generation textile-based
