Polydopamine particles-stabilized Pickering Emulsions

2023
Les émulsions stabilisées par des particules, connues sous le nom d'émulsions de Pickering, présentent une stabilité supérieure à celle des émulsions conventionnelles. Ces émulsions offrent la possibilité de réduire la quantité de tensioactifs utilisés, atténuant ainsi les risques pour la santé et l'environnement.La polydopamine (PDA) a suscité ...

Tailoring Pickering Double Emulsions by in Situ Particle Surface Modification

Langmuir, 2023
Fundamental studies on the formation and stability of Pickering double emulsions are crucial for their industrial applications. Available methods of double emulsion preparation involve multiple tedious steps and can formulate a particular type of double emulsion, that is, water-in-oil-in-water (w/o/w) or oil-in-water-in-oil (o/w/o).

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.

Recent Studies of Pickering Emulsions: Particles Make the Difference

Small, 2016
In recent years, emulsions stabilized by micro‐ or nanoparticles (known as Pickering emulsions) have attracted much attention. Micro‐ or nanoparticles, as the main components of the emulsion, play a key role in the preparation and application of Pickering emulsions.

Macroporous Polymer from Core−Shell Particle-Stabilized Pickering Emulsions

Langmuir, 2009
Poly(styrene-co-N-isopropylacrylamide) (PS-co-PNIPAM) core-shell particles were synthesized and used as particulate emulsifiers in the preparation of particle-stabilized (Pickering) emulsions. Highly concentrated oil-in-water emulsions with an internal phase up to 80 vol % can be produced using PS-co-PNIPAM core-shell particles along as the emulsifiers

Photocurable Pickering Emulsion for Colloidal Particles with Structural Complexity

Langmuir, 2008
We prepared polymeric microparticles with coordinated patches using oil-in-water emulsion droplets which were stabilized by adsorbed colloidal polystyrene (PS) latex particles. The oil phase was photocurable ethoxylated trimethylolpropane triacrylate (ETPTA), and the particle-armored oil droplets were solidified by UV irradiation within a few seconds ...

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

Particle Shape Anisotropy in Pickering Emulsions: Cubes and Peanuts

Langmuir, 2013
We have investigated the effect of particle shape in Pickering emulsions by employing, for the first time, cubic and peanut-shaped particles. The interfacial packing and orientation of anisotropic microparticles are revealed at the single-particle level by direct microscopy observations.

Amphiphilic Pickering Emulsifiers Based on Mushroom-Type Janus Particles

Langmuir, 2015
Iron-based mushroom-type Janus particles consisting of a poly(sytrene-co-divinylbenzene) and a silica moiety both with controllable morphologies were successfully synthesized on the gram scale and investigated as surfactants for Pickering emulsions.

Pickering Stabilized Peptide Gel Particles as Tunable Microenvironments for Biocatalysis

Langmuir, 2013
We demonstrate the preparation of peptide gel microparticles that are emulsified and stabilized by SiO2 nanoparticles. The gels are composed of aromatic peptide amphiphiles 9-fluorenylmethoxycarbonyldiphenylalanine (Fmoc-FF) coassembled with Fmoc-amino acids with different functional groups (S: serine; D: aspartic acid; K: lysine; and Y: tyrosine).
