TLDR
In this paper, a novel nanocomposite hydrogels (NC gels) with a unique organic-inorganic (clay) network structure have been synthesized by in-situ free radical polymerization.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.read more

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.

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).
