Journal ArticleDOI
Scaling behaviour of the rheology of aggregate networks formed from colloidal particles
TL;DR: The instantaneous shear modulus G and compactive strength Py of aggregate networks formed from silica particles with a mean diameter of 26 nm have been determined as a function of particle concentration as mentioned in this paper.
Journal ArticleDOI
The rheology of strongly-flocculated suspensions
TL;DR: In this paper, the authors investigated the rheology of strongly-flocculated dispersions of colloidal particles in a continuous network and showed that these networks possess a true yield stress in both shear and uniaxial compression (as realised in a centrifuge).
Journal ArticleDOI
Viscoelastic properties of strongly flocculated polystyrene latex dispersions
TL;DR: In this paper, the effects of shear degradation on the viscoelastic properties of polystyrene latex dispersions have been investigated and the effect of prolonged shearing has been shown to reduce both the true and extrapolated Bingham yield stress and the shear modulus.
Journal ArticleDOI
Electrokinetic studies of colloidal silica particles dispersed in non-aqueous media in the presence of a nonionic surfactant, dodecylhexaethylene glycol monoether (C12E6)
TL;DR: In this article, the change in charge on the addition of C12E6, acid (terephthalic acid) and salt (KCl) was studied using measurements of electrophoretic mobility and electrokinetic sonic amplitude (ESA).
Journal ArticleDOI
Viscoelastic and shear viscosity studies of colloidal silica particles dispersed in monoethylene glycol (MEG), diethylene glycol (DEG), and dodecane stabilized by dodecyl hexaethylene glycol monoether (C12E6).
TL;DR: Viscoelatic measurements of silica in monoethylene glycol at various surfactant concentrations showed a predominantly viscous response at low frequency and a predominantly elastic response at high frequencies, indicative of weak flocculation.
