The Primary Electroviscous Effect in Polystyrene Latices of Small Particle Size Range Prepared with the Addition of Anionic Surfactant as Emulsifier. Effect of Increasing Concentrations of Quaternary Ammonium Counterions of Different Ionic Sizes and Stability Characteristic of the Latices and the Latex–Electrolyte Mixtures

Electroviscous Effect of Moderately Concentrated Colloidal Suspensions

“…Despite these efforts, a satisfactory agreement with the experimental results is far from being achieved. Although some authors claim an agreement with Booth's theory, this is attained by modifying the value of some parameters of the theory in an advantageous way. , Most of the experimental papers are in the line of lack of agreement between theory and experimental results on the primary electroviscous effect. − In a series of papers, − the exact numerical solutions were corrected by the inclusion of a dynamic Stern layer (DSL), which was postulated by Zukoski and Saville. − Although the results showed a better agreement with the experiments, it was still insufficient. A detailed analysis of this correction showed that the relative increase of the theoretical results on the viscosity of the suspensions was not large enough to expect a much better agreement.…”

Electroviscous effect of concentrated suspensions in salt-free media: Water dissociation and CO2 influence

“…(7)- (13), neglecting products of small perturbation quantities, and applying the symmetry Eqs. (6), (20), and (21), the governing equations transform to…”

“…It is of small magnitude and its experimental determination is difficult [22,23]. Most of the experimental works [14][15][16][17][18][19][20][21] on the primary electroviscous effect find that it is underestimated by the theoretical models [24][25][26][27][28][29]. Various theories that try to predict the experimental results have been presented.…”

“…Consequently, the experimental study of the electroviscous effect is easier and can be performed with more confidence with salt-free suspensions. Apart from these requisites, the experiments must be performed with the same procedures as those in salt solutions [14][15][16][17][18][19][20][21].…”

“…(44) ensures that the electroneutrality of the cell is maintained when the flow field is imposed.According to the symmetry Eqs. (6),(20), and(21), the boundary conditions given by Eqs. (39)-(44) transform into…”
