Polymères microcellulaires à base d'émulsions concentrées (polyHIPE)

Plastiques et composites, 2012
L'emploi d'emulsions concentrees comme generatrices de materiaux polymeres microcellulaires a cellules ouvertes represente une alternative attractive aux methodes traditionnelles de moussage. Les materiaux ainsi obtenus, connus sous l'acronyme de polyHIPE, font l'objet d'un vif interet de la part des chercheurs academiques et industriels, du fait de ...

Synthesis of hydrogel polyHIPEs from functionalized glycidyl methacrylate

Polymer Chemistry, 2016
Highly porous hydrogels based on functionalized glycidyl methacrylate (GMA) have been successfully prepared through the high internal phase oil-in-water emulsions.

Ion exchange modules formed from polyhipe foam precursors

Chemical Engineering Journal, 1998
Abstract Homogeneous, highly porous, low density, open cellular polyhipe polymer (PHP) has been produced by polymerisation of a high internal phase emulsion. Its surface properties were modified by sulphonation. By incorporating Na + ions onto the sulphonated PHP surfaces a modular form of ion exchange resin capable of effective exchange with metal ...

High surface area polyHIPEs with hierarchical pore system

Soft Matter, 2009
The synthesis of polyHIPEs with bimodal pore-size distribution and very high specific surface areas up to 1210 m2 g−1 is reported. Monolithic polyHIPE precursors were swollen, and subsequently the polymeric network was crosslinked in the expanded state by internal and external electrophiles under catalysis of a Lewis acid leading to hypercrosslinked ...

Development of polyHIPE scaffolds for improved bone regeneration

2020
Critical size bone defects resulting from trauma or disease are challenging to treat due to the size and shape of the defect. Autologous tissue remains the gold standard due to the superior healing potential but harvesting material is challenging due to donor site complications.

PolyHIPEs: Recent advances in emulsion-templated porous polymers

Progress in Polymer Science, 2014
Abstract Porous polymers with well-defined porosities and high specific surface areas in the form of monoliths, films, and beads are being used in a wide range of applications (reaction supports, separation membranes, tissue engineering scaffolds, controlled release matrices, responsive and smart materials) and are being used as templates for porous ...

PolyHIPE loading with hydroxyapatite for biomedical applications

The polymerization of high internal phase emulsions (HIPEs) is a techniqueto create highly porous material, polyHIPE polymer. The pore size of polyHIPE porous foams can be changed from the sub-micron to micron range by varying the chemical composition of the emulsion and monomer ratio (styrene).
