Gel - Wikipedia
WEBA gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. 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.

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.
