Over the past few years, with the development of global industry and the increase of
population, the shortage of freshwater resources has prompted people to conduct in-depth …

Hydrogels, as the most typical elastomer materials with three‐dimensional (3D) network
structures, have attracted wide attention owing to their outstanding features in fields of …

Robust ionic sensing materials that are both fatigue-resistant and self-healable like human
skin are essential for soft electronics and robotics with extended service life. However, most …

Zwitterionic hydrogels have received great attention due to their excellent nonfouling and
biocompatible properties, but they suffer from weak mechanical strength in the saline …

Hydrogels from biological sources are expected as potential structural biomaterials, but most
of them are either soft or fragile. Here, a new strategy was developed to construct hydrogels …

Novel soft materials should comprise multiple supramolecular nanostructures whose
responses (for example, assembly and disassembly) to external stimuli can be controlled …

A dual physical crosslinking (DPC) strategy is used to construct moldable hydrogels with
ultrahigh strength and toughness. First, polyelectrolyte complex (PEC) hydrogels are …

Hydrogels are frequently used biomaterials due to their similarity in hydration and structure
to biological tissues. However, their utility is limited by poor mechanical properties, namely …

This review is an extensive evaluation and essential analysis of the design and formation of
hydrogels (HGs) for drug delivery. We review the fundamental principles of HGs (their …

The double-network (DN) structure is a state-of-the-art strategy used for toughening soft
materials. The challenge for widespread applications, however, is the difficulty in …
