Pickering Emulsions Stabilized by Monodisperse Latex Particles:  Effects of Particle Size

Langmuir, 2001
The preparation, type, and stability of emulsions of oil and water stabilized solely by spherical, monodisperse polystyrene latex particles of different size is described. Two types of behavior occur depending on whether particles remain intact (in the case of cyclohexane) or dissolve to give free polymer chains (in the case of toluene).

Development of stable Pickering emulsions/oil powders and Pickering HIPEs stabilized by gliadin/chitosan complex particles

Food & Function, 2017
In this paper, we demonstrate the use of gliadin/chitosan complex particles (GCCPs) as particulate stabilizers of oil-in-water emulsions of natural oils and water.

Hydrophilic and hydrophobic modifications of colloidal silica particles for Pickering emulsions

Journal of Colloid and Interface Science, 2017
Colloidal silica particles, functionalized with hydrophilic and hydrophobic groups, have been studied for utilization in particle-stabilized emulsions, so called Pickering emulsions. The amounts of attached groups have been characterized using NMR spectroscopy and elemental analysis. A range of particles were prepared, with sizes from around 13 to 70nm

Pickering Emulsions Stabilized by a Lipophilic Surfactant and Hydrophilic Platelike Particles

Langmuir, 2009
Liquid paraffin-water emulsions were prepared by homogenizing oil phases containing sorbitan oleate (Span 80) and aqueous phases containing layered double hydroxide (LDH) particles or Laponite particles. While water-in-oil (w/o) emulsions are obtained by combining LDH with Span 80, the emulsions stabilized by Laponite-Span 80 are always o/w types ...

Pickering emulsions stabilized by paraffin wax and Laponite clay particles

Journal of Colloid and Interface Science, 2009
Emulsions containing wax in dispersed droplets stabilized by disc-like Laponite clay particles are prepared. Properties of the emulsions prepared at different temperatures are examined using stability, microscopy and droplet-size analysis. At low temperature, the wax crystals in the oil droplets can protrude through the interface, leading to droplet ...

Novel Micro- and Nano-particles Cellulose Based Pickering Emulsions.

MRS Proceedings, 2011
AbstractEmulsions are usually metastable systems of two non-miscible phases stabilized by surface active species like surfactant molecules. Emulsions stabilized by solid colloidal particles adsorbed at the interface (Pickering emulsions) offer some competitive advantages with respect to classical emulsions.

Internally structured pickering emulsions stabilized by clay mineral particles

Journal of Colloid and Interface Science, 2009
The present study aims to describe emulsion particles containing a dispersed phase composed of nanostructured lipid mesophases and stabilized by montmorillonite and/or Laponite clay platelets. The size distributions of these emulsion particles were found independent of the clay mineral content and of the initial internal composition that determines the

Small angle scattering model for Pickering emulsions and raspberry particles

Journal of Colloid and Interface Science, 2010
Pickering emulsions, raspberry particles and other colloidal particle complexes are often characterized using small angle scattering techniques. The present work derives an analytical scattering model that accounts for the self-correlation of a spherical core and surface adsorbed particles as well as the particle-particle and core-particle correlation ...

Influence of particle concentration on multiple droplet formation in Pickering emulsions

Journal of Colloid and Interface Science, 2019
Multiphase droplets form when oil and water are mixed together at the ambivalent conditions that occur close to phase inversion. In this paper we propose a mechanism for the stabilisation of multiphase droplets by a single population of particles.We investigated the microstructure of emulsions formed when dodecane and water are mixed in the presence of

Pickering Foams : Particle Design and Catalysis

Mousses de Pickering : Conception de Particules et Catalyse Les particules colloïdales de silice sont des objets versatiles permettant la genèse de mousses dites de Pickering. Ces mousses peuvent être utilisées pour concevoir des nouveaux microréacteurs catalytiques gaz-liquide-solide (G-L-S).
