Gel - Wikipedia
WebA gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. [1] [2] Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady state, although the liquid phase may still diffuse through this system. [3] IUPAC definition for a gel.

WebJul 1, 2015 · There are many examples of these that we use routinely. Gelatine, that forms a 3D network able to trap water, is a good example. This property of gelatine led to the name we still use for these materials today: gels. This term was coined by Scottish chemist Thomas Graham in the 19th century.

Gels: Introduction - ScienceDirect
WebJan 1, 2001 · Gels are defined as “polymers and their swollen matters with three-dimensional (3D) network structures that are insoluble in any solvents.” Gels are cross-linked 3D networks that absorb solvents and swell to a limited degree without dissolution. They exist in states that are somewhere between a solid and a liquid.
