摘要

Sodium alginate/poly(vinyl alcohol) double-network fibers are fabricated

via

a facile and green procedure

which overcome the trade-off between strength and toughness without sacrificing the aqueous stability and biodegradability.

Abstract

Seaweed polysaccharide-based fibers featuring incomparable merits

such as green fabrication procedures and intrinsic functionalities

are promising sustainable alternatives to petrochemical fibers that threaten both the ecological environment and human health. However

achieving simultaneously high strength

toughness

and stability of seaweed polysaccharide fibers remains a long-standing challenge owing to their low crystallinity and ionic crosslinks. Herein

we report a stretch-mediated network engineering strategy to overcome this limitation. Anisotropic architectures composed of dual-crosslinked sodium alginate and chemically crosslinked poly(vinyl alcohol) are prepared by pre-stretching. The highly ordered chemically crosslinked networks endow the fibers with high strength

and the anisotropic double networks prevent stress concentration and enable high toughness. The resultant fibers exhibit a tensile strength of 547.8 MPa

Young's modulus of 17.6 GPa

and toughness of 43.3 MJ/m

surpassing most regenerated biomass fibers. Ad

ditionally

fibers with an anisotropic network exhibit good aqueous stability

guaranteeing their usage in diverse solution environments and potential applications in triboelectric textiles. This study demonstrates a general and scalable strategy to decouple the strength–toughness trade-off in polysaccharide fibers without sacrificing biodegradability

thereby providing new insights into the structural design of robust

stable

and sustainable biomass-based fibers.
