Controlled microphase separation and strain programming in hydrogel fibers toward biomimetic architectures and properties.

ABSTRACT: In contrast to conventional high-strength, high-modulus fibers, spider silk uniquely combines high toughness, strength and diverse functionalities, enabling spiders to thrive in natural environments. However, replicating the sophisticated architecture and properties of spider silk through synthetic approaches, particularly via scalable fiber manufacturing processes, remains a formidable challenge. Herein, we report the tailored fabrication of spider silk-like structures in sodium polyacrylate and polyacrylamide (PANa-PAM) composite polymer hydrogel fibers via wet-spinning. The antisolvent-induced phase separation process modulates composite polymer microphase, yielding nascent PANa-PAM fibers abundant in hydrogen-bonded nanoclusters.
