Nature endows numerous organisms with the ability to realize their basic physiological
activities through stimulus-responsive actuation. Inspired by these interesting biological …

Double-network (DN) gels have drawn much attention as an innovative material having both
high water content (ca. 90 wt%) and high mechanical strength and toughness. DN gels are …

DOI: 10.1002/adma. 201503724 high strength of 2 MPa, high fracture energy of 9300 J m−

The ever increasing improvements of pharmaceutical formulations have been often obtained
by means of the use of hydrogels. In particular, environmentally sensitive hydrogels have …

Hydrogels have long been explored as attractive materials for biomedical applications given
their outstanding biocompatibility, high water content, and versatile fabrication platforms into …

In this review, we survey recent literature (2009–2013) on hydrogels that are mechanically
tough and adhesive. The impact of published work and trends in the field are examined. We …

Many polymer networks and gels display nanostructural heterogeneity in the form of
spatially inhomogeneous crosslinking densities, along with additional topological defects …

In this review we highlight new developments in tough hydrogel materials in terms of their
enhanced mechanical performance and their corresponding toughening mechanisms …

Three kinds of novel hydrogels with excellent mechanical performance have been
developed, based on different concepts. Two of them exhibit high resistance to extension, up …

In this work, the authors succeed in direct visualization of the network structure of synthetic
hydrogels with transmission electron microscopy (TEM) by developing a novel staining and …
