Tailoring the morphology of poly(high internal phase emulsions) synthesized by using deep eutectic solvents

e-Polymers, 2020
High internal phase emulsions (HIPEs) are among complex biphasic fluids that expand on the traditional emulsion compositions, for instance, for the preparation of macroporous polymers by emulsion templating.

Post Polymerisation Hypercrosslinking with Emulsion Templating for Hierarchical and Multi-Level Porous Polymers

Acta Chimica Slovenica, 2020
Porosity in polymers and polymeric materials adds to their functionality due to achieving the desired tailored characteristics porosity offers, such as improved mass transfer through the material, improved accessibility of reactive sites, reduced overall

Injectable PolyHIPEs as High-Porosity Bone Grafts [PDF]

Biomacromolecules, 2011
Polymerization of high internal phase emulsions (polyHIPEs) is a relatively new method for the production of high-porosity scaffolds. The tunable architecture of these polyHIPE foams makes them attractive candidates for tissue engineered bone grafts.

Antimicrobial activity of silver composites obtained from crosslinked polystyrene with polyHIPE structures

Polímeros, 2021
The literature reports several potential applications of polymers prepared with high internal phase emulsions (HIPEs). However, the evaluation of these materials as supports for antimicrobial agents has not been explored.

Polyethyleneimine Loading into High Internal Phase Emulsion Polymer for CO₂ Adsorption: Synthesis and Characterization of the PolyHIPE

Chemical Engineering Transactions, 2012
The purpose of this research was to synthesize the new type of adsorbent for CO2 adsorption. The polymer obtained from high internal phase emulsion or “polyHIPE” can be polymerized from divinylbenzene (DVB) and vinyl benzyl chloride (VBC ...

Highly permeable macroporous polymers synthesized from pickering medium and high internal phase emulsion templates [PDF]

, 2010
Open porous poly-Plckerlng-M/HIPEs with permeabilities of up to 2.6 D were prepared by polymerisation of PickeringM/HIPEs to which small amounts of surfactant were added.

Effect of Amines on High Internal Phase Emulsion Adsorbents for Carbon Dioxide Adsorption

Chemical Engineering Transactions, 2013
High internal phase emulsion polymers (PolyHIPE) with amine, i.e. hexylamine, were prepared. The oil-in-water emulsion system was obtained by mixing divinylbenzene, vinylbenzylchloride and surfactants, SpanR 80 (oil soluble surfactant) and Triton X-100 ...

Acrylic Acid “Reversed” PolyHIPEs

Macromolecular Rapid Communications, 2005
AbstractSummary: An oil‐in‐water high internal phase emulsion consisting of acrylic acid, water, and a crosslinker (N,N′‐methylene bisacrylamide) as the water phase, and toluene as the oil phase was successfully stabilised to sustain thermal initiation of radical polymerisation resulting in porous open‐cellular monolithic material.

Application of PolyHIPE Membrane with Tricaprylmethylammonium Chloride for Cr(VI) Ion Separation: Parameters and Mechanism of Transport Relating to the Pore Structure

Membranes, 2018
The structural characteristics of membrane support directly affect the performance of carrier facilitated transport membrane. A highly porous PolyHIPE impregnated with Aliquat 336 is proposed for Cr(VI) separation.
