Physically crosslinked hydrogels can be prepared by different methods depending on the nature of the crosslink involved. Polyvinyl alcohol hydrogels are usually produced by the freeze-thaw technique.

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.

Dec 18, 2024 · Hydrogels are versatile biomaterials that have gained a significant amount of interest from various industries. A hydrogel is a three-dimensional structure made of natural or synthetic …

Nov 1, 2023 · Hydrogels are hydrophilic, three-dimensional and cross-linked polymeric networks capable of imbibing water or biological fluids approximately 10–20 times of their initial weight (Ahmed, 2015).

Jul 25, 2025 · Hydrogels are materials composed of polymer chains that form a network capable of absorbing and holding significant amounts of water. This unique structure gives them a soft, jelly-like …

May 22, 2023 · 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 …

Mar 20, 2025 · Hydrogels are three-dimensional networks of hydrophilic polymers that absorb and retain large amounts of water while maintaining their structure. Their stability comes from chemical or …

Nov 21, 2022 · Eleonora D’Elia, a materials scientist at Imperial College London in England, describes hydrogels and many of their uses — from the fake snow on flocked Christmas trees, to absorbents in …

Hydrogels are hydrophilic polymers with three-dimensional network structures synthesized from natural or synthetic materials and have been developed for a variety of biomedical applications, including …

Hydrogels are crosslinked polymer chains with three-dimensional (3D) network structures, which can absorb relatively large amounts of fluid. Because of the high water content, soft structure, and …
