“…Since a NC hydrogel composite with inorganic nanoparticle was first studied by Haraguchi and Takehisa in 2002, nanoparticle composite hydrogels have received considerable attention in drug delivery, tissue engineering, and wastewater treatment . A wide range of nanoparticles have been used for hydrogel reinforcement, including polymeric particles (nanogels, core‐shell particles, dendrimers, hyperbranched polymers, liposomes, polymer micelles), inorganic particles (e.g., hydroxyapatite, silicate) and metal/metal oxide particles (e.g., silver, gold, ZnO, TiO 2 ).…”

Hydrogels are a class of polymeric network materials embedded in a water-rich environment. They are widely applied in drug delivery, actuator, and sensor. However, conventional hydrogels encountered limits from their poor mechanical property. Recent researches in hydrogels have been focusing on mechanical enhancement, ranging from design of microstructures to adjustment of compositions in hydrogels. Here, the design and fabrication strategies of high-strength hydrogels, as well as major progress in their typical strength-support applications are systemically reviewed.

“…In the ternary system, BZI‐2A replaces PEG chains and complex with α‐CD. However, when sparing the ternary solution with CO 2 , PPR hydrogel has been regenerated, which implies that the interaction between BZI‐2A + and α‐CD becomes weaker than that of PEG with α‐CD when the BZI‐2A is converted to the BZI‐2A + …”

Realizing the reversible transformation of the supramolecular hydrogels is essential for their application as smart materials. The reversible sol‐gel transition of the polypseudorotaxane (PPR) hydrogels is achieved through adding a CO2‐switchable guest molecule into the PPR hydrogel of poly(ethylene glycol) (PEG) and α‐cyclodextrins (α‐CDs). Alternating treatments with CO2 and heating drive such reversible transition due to the competitive complexation as evidenced by 2D NOESY 1H NMR and isothermal titration calorimetry as well as X‐ray diffraction. The present work describes a straightforward way to obtain switchable PPR hydrogels triggered by a compatible stimulus of CO2. These stimuli‐responsive PPR hydrogels have potential applications as biomaterials.

“…[178,179] Approaches including those related to the molecular weights, distribution sequence of the hydrophobic groups, type, and content of the hydrophobic groups, type and content of the ionic groups, and relative positions of the hydrophobic and ionic groups can be adopted to improve the hydrophobic association ability of HAPEs and HAPs. [180][181][182][183][184] When the concentration of the hydrophobic monomer was above the critical micellar concentration (CMC), the hydrophobic monomers formed stable hydrophobic association domains in the presence of a surfactant. Meanwhile, intermolecular hydrophobic interactions or micro-block copolymerization lead to the formation of a three-dimensional network of polymer chains, resulting in a rapid increase in the apparent viscosity, [178] in which the mixed micelles of the hydrophobic groups and surfactants would act as crosslinking points [179,185] (Fig.…”

Hydrogels are a series of soft and wet materials with three dimensions of crosslinked networks. Hydrogels have attracted great attention due to their diverse functional properties, and their wide range of applications, such as in soft robots and actuators, stretched electronic devices, tissue engineering materials, controlled-release drug delivery vehicles, biomedicine materials, food science, and (bio)sensors. In general, there are four core concerns in hydrogel science, including the polymer source, structure fabrication, gel function, and gel applications. According to the logic that the "structure determines function", it is believed that rational design of structures can effectively regulate the functions and applications of hydrogels. Hence, in the current review, "structure" as the core topic will be highly regarded, and the crosslinking mechanisms and structural diversity of hydrogels are comprehensively summarized. Additionally, hydrogels also show their great application potential in food science. Hence, the current review also pays more attention to the application of hydrogels in food nutrition and health, food engineering and processing, and food safety. It is whished that this review not only serves as a reference for improving the comprehensive understanding of the structural design of hydrogels but also provides a forward-looking idea for hydrogel applications in food science.
