Fabrication of double imprinted anchor points in cellulose nanocrystals-based hierarchical porous polyHIPEs for selective separation of flavoniods under physiological pH.

Journal of Hazardous Materials, 2023
Previous research had proved that molecular imprinted polymers can be used as separation material for removing Naringin (NRG) from agricultural pomelo wastes effectively.

Cellulose-based, flexible polyurethane polyHIPEs with quasi-closed-cell structures and high stability for thermal insulation.

Carbohydrate Polymers, 2022
Cellulose-based, closed-cell porous materials templated from emulsions are promising for thermal insulation, but their low stability imposed by physical interaction hinders the materials from real applications.

Inherently reactive polyHIPE material from dicyclopentadiene

Chemical Communications, 2010
A simple formulation of a stable high internal phase emulsion of dicyclopentadiene which is cured by using properly selected ring opening metathesis polymerization initiators yields highly porous monolithic materials with paramount mechanical properties and the possibility of easy functionalisation.

Hierarchical Porous Polystyrene Monoliths from PolyHIPE

Macromolecular Rapid Communications, 2015
Hierarchical porous polystyrene monoliths (HCP-PolyHIPE) are obtained by hypercrosslinking poly(styrene-divinylbenzene) monoliths prepared by polymerization of high internal phase emulsions (PolyHIPEs). The hypercrosslinking is achieved using an approach known as knitting which employs formaldehyde dimethyl acetal (FDA) as an external crosslinker ...

Mechanically tunable PDMS-based polyHIPE acoustic materials

Journal of Materials Chemistry C, 2022
Porous PDMS elastomers were synthesized using emulsion templated thiol–ene “click” reactions to obtain materials with tunable storage moduli at a single porosity value that achieve low sound speed values of ∼40 m s−1.

Supporting ruthenium initiator on PolyHIPE

Journal of Molecular Catalysis A: Chemical, 2006
Abstract PolyHIPE samples were successfully synthesised using divinylbenzene and styrene as polymerisable continuous phase, aqueous phase containing potassium persulphate and calcium chloride dihydrate, a mixture of emulsifiers (SPAN20, CTAB and DDBSS) and toluene as a porogen.

Effect of Cosurfactant on Structure and Properties of Polymerized High Internal Phase Emulsions (PolyHIPEs).

Langmuir, 2021
Porous polymerized high internal phase emulsion (polyHIPE) monoliths are synthesized by using Span 80 with different cosurfactants. The results reveal that the void size can be reduced by employing cosurfactants, except for Tween 20.

Synthesis and functionalisation of polyHIPE® beads

Reactive and Functional Polymers, 2002
Discrete spheroidal particles of interconnected microcellular foams were synthesised by suspension polymerisation of a high internal phase emulsion. These particles have been surface-grafted with functionalised macromolecular chains by controlled radical polymerisation using a covalently-bond TEMPO initiator.

Biodegradable Fumarate-Based PolyHIPEs as Tissue Engineering Scaffolds

Biomacromolecules, 2007
PolyHIPEs show great promise as tissue engineering scaffolds due to the tremendous control of pore size and interconnectivity afforded by this technique. Highly porous, fully biodegradable scaffolds were prepared by polymerization of the continuous phase of high internal phase emulsions (HIPEs) containing the macromer poly(propylene fumarate) (PPF) and

Polymerization of Dicyclopentadiene/Styrene in PolyHIPE

Materials Science Forum, 2015
A series of porous poly(styrene-divinylbenzene) monoliths (polyHIPE) was synthesized by high internal phase emulsions (HIPE). The effects of the ethanol contents on the microstructure of the polyHIPE were characterized by scanning electron microscopy and mercury intrusion porosimeter.
