Nanocellulose-stabilized Pickering emulsions and their applications
Pickering emulsion, which is an emulsion stabilized by solid particles, offers a wide range of potential applications because it generally provides a more stable system than surfactant-stabilized emulsion. Among various solid stabilizers, nanocellulose may open up new opportunities for future Pickering emulsions owing to its unique nanosizes, amphiphilicity, and other favorable properties (e.g....
متن کاملPickering emulsions stabilized by surface-modified Fe3O4 nanoparticles.
Unmodified Fe(3)O(4) nanoparticles do not stabilize Pickering emulsions of a polar oil like butyl butyrate. In order to obtain stable emulsions, the Fe(3)O(4) nanoparticles were modified by either carboxylic acid (RCOOH) or silane coupling agents (RSi(OC(2)H(5))(3)) to increase their hydrophobicity. The influence of such surface modification on the stability of the resultant Pickering emulsions...
متن کاملThermodynamically stable pickering emulsions.
We show that under appropriate conditions, mixtures of oil, water, and nanoparticles form thermodynamically stable oil-in-water emulsions with monodisperse droplet diameters in the range of 30-150 nm. This observation challenges current wisdom that so-called Pickering emulsions are at most metastable and points to a new class of mesoscopic equilibrium structures. Thermodynamic stability is demo...
متن کاملAdsorption Dynamics in Pickering Emulsions
We investigate the adsorption dynamics of colloidal particles to a liquid/liquid interface. Such an analysis is important in the formation of Pickering emulsions. Using a free energy formulation that has been used for adsorption of surfactants, we obtain the time evolution of the surface coverage and dynamic surface tension. We estimate the characteristic time for adsorption, and show that it c...
متن کاملNon-aqueous Isorefractive Pickering Emulsions
Non-aqueous Pickering emulsions of 16-240 μm diameter have been prepared using diblock copolymer worms with ethylene glycol as the droplet phase and an n-alkane as the continuous phase. Initial studies using n-dodecane resulted in stable emulsions that were significantly less turbid than conventional water-in-oil emulsions. This is attributed to the rather similar refractive indices of the latt...
