Abstract
Novel nanocomposite hydrogels (NC gels) with a unique organic-inorganic (clay) network structure (see Figure) have been synthesized by in-situ free radical polymerization. The resulting NC gels exhibit high structural homogeneity, superior elongation with near-complete recovery, good swellability, and rapid deswelling in response to temperature changes.

Highly stretchable and tough hydrogels

TL;DR: The synthesis of hydrogels from polymers forming ionically and covalently crosslinked networks is reported, finding that these gels’ toughness is attributed to the synergy of two mechanisms: crack bridging by the network of covalent crosslinks, and hysteresis by unzipping thenetwork of ionic crosslinks.

Biomimetic 4D printing

TL;DR: In this article, a plant-inspired shape morphing system is presented, where a composite hydrogel architecture is encoded with localized, anisotropic swelling behavior controlled by the alignment of cellulose fibrils along prescribed four-dimensional printing pathways.

Why are double network hydrogels so tough

TL;DR: In this article, double-network gels are characterized by a special network structure consisting of two types of polymer components with opposite physical natures: the minor component is abundantly crosslinked polyelectrolytes (rigid skeleton) and the major component comprises of poorly cross-linked neutral polymers (ductile substance).

Physical hydrogels composed of polyampholytes demonstrate high toughness and viscoelasticity

TL;DR: It is reported that polyampholytes, polymers bearing randomly dispersed cationic and anionic repeat groups, form tough and viscoelastic hydrogels with multiple mechanical properties.
