Influence of the particle type on the rheological behavior of Pickering emulsions

Influence of Nanoparticles and Drop Size Distributions on the Rheology of w/o Pickering Emulsions

“…Aveyard et al [7] discussed the influence of solid particle concentration (up to 6 wt %) and dispersed phase fraction on phase inversion, droplet diameter, and viscosity in water-toluene emulsions. Shear thinning rheological behavior was reported amongst others by Barman and Christopher [18], Chen et al [19], Chen et al [20], Torres et al [21], and Whitby and Garcia [22]. Furthermore, investigations concerning the viscoelastic behavior of Pickering emulsions were carried out by Sharma et al [23].…”

Effect of the degree of substitution of octenyl succinic anhydride-banana starch on emulsion stability

“…As shown previously, the presence of OSA-banana starch granules located as a closely packed layer at the oil/water interface provides a mechanism for stabilization through the steric hindrance of the particles (Torres et al, 2007), allowing an increase in G in the samples as a consequence of a highly flocculated elastic structure (Chen et al, 2011). According to criteria proposed by Torres et al (2007), emulsions with OSA-banana starch are physically stable due to their rheological response.…”

A pH responsive Pickering emulsion stabilized by fibrous palygorskite particles

“…The long term physical stability of emulsions can be assessed through rheology measurements, as deformation results in energy storage (Lagaly et al, 1999b;Torres et al, 2007;Chen et al, 2011;Whitby and Garcia, 2014). Compressed emulsions result in further deformation of the dispersed phase droplets, increasing their surface area and thereby storing elastic energy (Torres et al, 2007).…”
