Rheology of High Internal Phase Emulsions

Langmuir, 2006
The mechanical dispersion technology used in this study employs rotor-stator mixers that produce water-continuous high internal phase emulsions (HIPEs) with narrow drop size distributions and small drop sizes, even when the internal phase (oil) viscosity is quite high.

High-internal-ionic liquid-phase emulsions

Chem. Commun., 2012
High-internal-ionic liquid-phase emulsions were formed for the first time. The novel emulsions are very stable and do not involve any volatile organic solvent. They have great potential of applications in different fields, such as material synthesis, extraction, encapsulation, and chemical reactions.

Edible high internal phase Pickering emulsion with double-emulsion morphology

Food Hydrocolloids, 2021
Abstract Food-grade high internal phase Pickering emulsions (HIPPEs) unify the stability of Pickering emulsions and the advantages of detergent-based high internal phase emulsions (HIPEs), making them attractive as nutritional products. However, as oral delivery systems, HIPPEs are usually prepared in the form of o/w emulsions, which are suitable ...

Chitin Nanocrystals for Pickering High Internal Phase Emulsions

Biomacromolecules, 2014
Chitin is a natural polymer of glucosamine bearing N-acetyl groups. Chitin nanocrystals (ChiNCs), resulting from the acid hydrolysis of amorphous regions of chitin, are crystalline positively charged rod-like particles. ChiNCs show some interfacial properties and very efficiently stabilize oil/water interfaces, leading to the so-called Pickering ...

Structure of high-internal-phase-ratio emulsions

Journal of Colloid and Interface Science, 1974
The structure of high-internal-phase-ratio emulsions was treated, theoretically and mathematically, in a paper presented at the National Colloid Symposium in 1966 (1). At that time, certain postulates were proposed to explain the rheological properties of these emulsions on the basis of the geometry of the particle packing.

RHEOLOGICAL PROPERTIES OF HIGH INTERNAL PHASE RATIO EMULSIONS

International Symposium on Liquid-Liquid Two Phase Flow and Transport Phenomena, 1997
W/O high internal phase ratio emulsions (HIPRE) with three different dispersed phase volumes of 80, 88 and 94% were prepared with 1% sorbitol solution as the aqueous phase, light mineral oil as the oil phase and polyoxyethylene (2) oleylether as the surfactant. Viscosities of the emulsions were measured as a function of the rate of premixing before the

Polymerization and carbonization of high internal phase emulsions

Polymer International, 2004
AbstractHigh internal phase emulsions (HIPEs) of styrene and divinylbenzene (DVB), with 0–40 % vinylbenzyl chloride (VBC) in the oil phase, were polymerized to give porous polymers (pore volumes 84–92 %), which were sulfonated and carbonized at temperatures up to 700 °C to obtain macroporous carbon monoliths. On carbonization, overall sample dimensions

On the formation and stability of high internal phase O/W emulsions

Advances in Colloid and Interface Science, 2006
High internal phase o/w emulsions have been investigated with respect to stability. A series of aliphatic hydrocarbons were used as the oil component. By matching the refractive index of both phases, transparent, concentrated emulsions were produced and these emulsions were found to have the highest long-term stability.

Rheology of high internal phase ratio emulsions

Food Hydrocolloids, 2006
The rheology of high internal phase ratio oil-in-water emulsions was investigated experimentally using a controlled-stress rheometer. Steady shear, oscillatory shear, and creep/recovery measurements were carried out on a series of highly concentrated fine (Sauter mean radius 1.28 μm), coarse (Sauter mean radius 1.95 μm), and mixed fine-and-coarse ...

High internal phase emulsion with double emulsion morphology and their templated porous polymer systems

Journal of Colloid and Interface Science, 2016
This paper reports synthesis of the first high internal phase emulsion (HIPE) system with double emulsion (DE) morphology (HIPE-DE). HIPE is a highly concentrated but highly stable emulsion system, which has a dispersed/internal phase fraction over 74vol%. DE represents an emulsion system that hierarchically encapsulates two immiscible phases.
