Determination of critical gel-sol transition point of Highly
In terms of rheological behavior, gel exhibits viscoelastic behavior, meaning that it is an intermediate material between a solid (elastic) and liquid (viscous) phase. Therefore,
Some Thoughts on The Definition of a Gel | SpringerLink
Solid-like gels are characterized by the absence of an equilibrium modulus, by a storage modulus, G′(ω), which exhibits a pronounced plateau extending to times at least of the order of seconds,
Rheological Properties of Coordinated Physical Gelation and
The gel points were determined by identifying where the loss modulus (G'''') and storage modulus (G'') intersect (tan(δ) = 1) . Although gel points are informative for defining the transition of
The rheological properties of gels, (A) storage and loss modulus
The rheological properties of gels, (A) storage and loss modulus as a function of angular frequency for the gels; (B) recovery of the gel, which was first subjected to a large strain of
