Hydrogel - Wikipedia
A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [1] [2] The solid phase is a water insoluble three dimensional network of polymers, having absorbed a large amount of water or biological fluids.

In the present review, we focused on the fundamental concepts of hydrogels—classification, the polymers involved, synthesis methods, types of hydrogels, properties, and applications of the hydrogel. Hydrogels can be synthesized from natural ...
Hydrogel: Preparation, characterization, and applications: A review
Hydrophilic gels that are usually referred to as hydrogels are networks of polymer chains that are sometimes found as colloidal gels in which water is the dispersion medium [1]. Researchers, over the years, have defined hydrogels in many different ways.
Hydrogels: Definition, History, Classifications, Formation ...
2023年5月22日 · Hydrogels are three-dimensional (3D) structured networks of crosslinked hydrophilic polymer matrices capable of holding a large amount of water (> 10%by definition) and displaying useful characteristics such as softness, toughness, biocompatibility, stretchability, and …
Hydrogels: Methods of Preparation, Characterisation and …
Edible gels are used widely in the food industry and mainly refer to gelling polysaccharides (i.e. hydrocolloids) (Phillips & Williams, 2000). The term hydrogel describes three-dimensional network structures obtained from a class of synthetic and/or natural polymers which can absorb and retain significant amount of water (Rosiak & Yoshii, 1999).
Hydrogel - an overview | ScienceDirect Topics
A hydrogel is a network of hydrophilic polymers that are crosslinked either through physical entanglement (reversible hydrogel) or covalent bonds (permanent hydrogel), whilst a gel is a semi-solid material of hydrophilic polymers consisting of large amounts of liquid and small amounts of solids.
