Rheological aspects of xanthan gum: Governing factors and

Section 3 introduces the fundamental rheological principles of XG and commonly used rheological models in WBDFs and EOR. It further analyzes the major factors that influence the rheological

Influence of Crosslink Density on Electrical

To investigate the influence of the crosslinked polyethylene (XLPE) structure on electrical performance, various analytical methods were employed to study polyethylene structures with different degrees of crosslinking. Dynamic

Basics of rheology

The storage modulus G'' (G prime, in Pa) represents the elastic portion of the viscoelastic behavior, which quasi describes the solid-state behavior of the sample. The loss modulus G'''' (G double prime, in Pa) characterizes the

Rheological Properties of Honey from Burkina

[Citation 3] The rheological properties influence the sensory quality of honey and also affect a number of technological operations, such as heating, mixing, at all the temperatures analysed (5, 10, 15, 20, 25, 30, and 40°C).

Influence of cross-link density on the properties of ROMP thermosets

Storage modulus (E′) and loss modulus (E″) are determined from the in phase and out of phase response of the materials to an applied oscillating strain. The storage modulus

A Review on Rheological Properties and

Roach et al. suggested that the influences of salt on the protein solubility affect the dough properties. Salt decreases the solubility of protein in the wheat flour dough as its concentration increases. Salvador et al. (2006) found

6 FAQs about [Influence on rheological storage modulus]

Why do viscoelastic solids have a higher storage modulus than loss modulus?

Viscoelastic solids have a higher storage modulus than loss modulus due to the presence of links inside the material, such as chemical bonds or physical-chemical interactions. This is represented by G' > G'' in the material's properties.

What is the difference between storage modulus and loss modulus?

The storage modulus G′ characterizes the elastic and the loss modulus G″ the viscous part of the viscoelastic behavior. The values of G′ represent the stored energy, while G″ stands for the deformation energy that is lost by internal friction during shearing [35, 36]. Until the gelation point (t c) G″ is larger than G’.

What is the loss modulus G''?

The loss modulus G'' (G double prime, in Pa) characterizes the viscous portion of the viscoelastic behavior, which can be seen as the liquid-state behavior of the sample. Viscous behavior arises from the internal friction between the components in a flowing fluid, thus between molecules and particles.

What is the rheological behavior of a forming hydrogel?

Gelation tracking The rheological behavior of the forming hydrogel is monitored as a function of time, following the shear storage modulus G′ and the loss modulus G'' (Fig. 1). The storage modulus G′ characterizes the elastic and the loss modulus G″ the viscous part of the viscoelastic behavior.

Why are rheological and mechanical properties important in polymer processing?

From the point of view of processing and subsequent applications of the polymer, rheological and mechanical properties are particularly important. Rheological studies show that the disentangling of macromolecules leads to a decrease in the viscosity of polymer melt and a decrease in modulus values.

What is the complex shear modulus?

G* is the complex shear modulus, which describes the entire viscoelastic behavior of a sample. The phase shift δ, the time lag between the preset and the resulting sinusoidal oscillation, is determined for each measuring point. This angle, always between 0° and 90°, is now placed below the G* vector.
