Azine- and Imine-linked Conjugated PolyHIPEs through Schiff-Base Condensation Reaction
Polymer Chemistry, 2021A new type of transition metal-free π-conjugated polyHIPEs is obtained by a Schiff-base condensation reaction coupled with a concentrated emulsion-based templating technique.

Journal of Applied Polymer Science
In this study, high internal phase emulsions (HIPEs) with ranging vinyl benzyl chloride (VBC) contents (50–80 v/v%) were prepared to synthesize polyHIPEs with 90% nominal porosity having different ratios of Cl content.

A new route to carbon black filled polyHIPEs
Soft Matter, 2006A series of carbon black filled polyHIPEs was synthesised following a new preparation protocol. 1 wt% carbon black was dispersed in the monomer mixture. In order to enhance the stability of the suspension, polymer grafting of carbon black was performed by initiating the polymerisation prior to emulsifying the formulation. All of the carbon black filled

Preparation of hypercrosslinked PolyHIPEs by using a bio-derived monomer
European Polymer Journal, 2021The interest on adapting bio-derived species to polymer synthesis has been increased in the last decade. Terpenes that can be obtained by extracting from the essential oils of tree sap and citrus fruit have an important place on this subject.

Polymerization of MMA in polyHIPEs by RATRP
Journal of Polymer Research, 2014A series of polymerized high internal phase emul- sions (polyHIPEs) with different cavities and windows (named PSD) were used as microreactors. Then methyl meth- acrylate (MMA) was polymerized in the spaces of the polyHIPE by reverse atom transfer radical polymerization (RATRP).

PolyHIPEs from Divinyl Adipate: Preparation and Degradability
Macromolecular Chemistry and Physics, 2013Using a high internal phase emulsion templating approach, highly porous open cellular polymers are prepared from divinyl adipate (DVA). The morphological structure of the monoliths includes cavities in the diameter range of around 5–25 μm and secondary interconnecting pores approximately 1 μm in diameter.

Interconnected highly porous poly(vinylamine) monoliths are produced by post-polymerization hydrolysis of emulsion-templated poly(N-vinylformamide) polyHIPEs (polymerized high internal phase emulsions). Unlike previous work, in which polyHIPEs were amine-

Ionic Liquids as Internal Phase for Non‐Aqueous PolyHIPEs
Macromolecular Rapid Communications, 2011AbstractStable high internal phase emulsions (HIPEs) with the ionic liquid 1‐ethyl‐3‐methylimidazolium bis(trifluoromethyl‐sulfonyl)imide as dispersed phase were prepared and polymerised thermally into polyHIPEs. All polyHIPEs exhibited pore morphologies similar to that of polyHIPEs obtained with an aqueous dispersed phase.

For the efficient extraction of lithium ions (Li+) from salt-lake brines, adsorbents with high adsorption capacity, fast equilibrium rate, and excellent selectivity are urgently needed. Herein, aminoethyl benzo-12-crown-4 (2AB12C4) functionalized polymer

A novel type of highly porous polymeric monolith called PolyHipe has been applied as a support for an immobilized catalyst (sulfonic acid). Somewhat differently from a conventional packed bed where the reaction mixture flows around the porous catalytic particles, here, the reaction mixture is forced through the pores of the monolith.
