Journal ArticleDOI
Highly stretchable and tough hydrogels
Jeong-Yun Sun,Xuanhe Zhao,Widusha R. K. Illeperuma,Ovijit Chaudhuri,Kyu Hwan Oh,David J. Mooney,David J. Mooney,Joost J. Vlassak,Zhigang Suo +8 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.
Journal ArticleDOI
Printing ferromagnetic domains for untethered fast-transforming soft materials
TL;DR: 3D printing of programmed ferromagnetic domains in soft materials that enable fast transformations between complex 3D shapes via magnetic actuation are reported, enabling a set of previously inaccessible modes of transformation, such as remotely controlled auxetic behaviours of mechanical metamaterials with negative Poisson’s ratios.
Journal ArticleDOI
Multi-scale multi-mechanism design of tough hydrogels: building dissipation into stretchy networks
TL;DR: It is shown that tough hydrogels generally possess mechanisms to dissipate substantial mechanical energy but still maintain high elasticity under deformation, and a particularly promising strategy for the design is to implement multiple mechanisms across multiple length scales into nano-, micro-, meso-, and macro-structures of hydrogel.
Journal ArticleDOI
A theory of coupled diffusion and large deformation in polymeric gels
TL;DR: A theory of the coupled mass transport and large deformation of a polymeric gel, which assumes that the local rearrangement of molecules is instantaneous, and model the long-range migration by assuming that the small molecules diffuse inside the gel.
Journal ArticleDOI
3D Printing of Highly Stretchable and Tough Hydrogels into Complex, Cellularized Structures

TL;DR: A 3D printable and highly stretchable tough hydrogel is developed by combining poly(ethylene glycol) and sodium alginate, which synergize to form a hydrogels tougher than natural cartilage.
