Polyester-glycidyl methacrylate (GMA)-based poly(high internal phase emulsion)s (polyHIPEs) with 85% internal phase were prepared by using unsaturated polyester resin (UPR), glycidyl metahacrylate and divinylbenzene (DVB) or styrene (St) with triethanolamine (TEA) as an emulsifier in the presence of a porogen. Porous monoliths were obtained by a removal of internal phase after curing of dispersed phase at 80°C. Morphologies and surface properties of obtained porous monoliths were investigated by scanning electron microscopy (SEM) and Brunauner-Emmet-Teller (BET) molecular adsorption methods. Amine functionalization of epoxy groups of polyHIPEs was achieved by reactions with several amines such as 1,4-ethylenediamine (EDA), 1,6-hexamethylenediamine (HMDA), 4-aminosalicylic acid (ASA), 2-aminothiazole (ATAL), 4-aminobenzothiazole (ABTAL) and 2-phenylimidazole (PIAL), respectively. The functionalized polyHIPEs were characterized by elemental analysis and the best result was obtained with the 1,4-ethylenediamine (EDA) ligand. The adsorption capacities of the modified monoliths for Ag(I), Cu(II) and Cr(III) were determined under non-competitive conditions at room temperature. The results showed that the maximum adsorption capacities of the modified monoliths decrease in order of Ag(I) > Cu(II) > Cr(III) and polyHIPE with 2-phenylimidazole (PIAL) groups is the most effective adsorbent for heavy metal ions.

“…[2][3][4][5] Several applications of these materials have been proposed in the literature, for example their use as ion exchange [6] and scavenger resins, [7,8] catalyst supports (immobilization of molecular catalysts), [9][10][11] as sensor materials, [12] or as biologically compatible substrates for tissue culture. [13][14][15] An outstanding feature of polyHIPEs is their high void fraction in combination with an open and accessible macroporosity resulting from the use of high internal phase emulsions (HIPEs) as templates.…”

A macroporous polyHIPE was used as a monolithic support to grow crystals of the metal‐organic framework Cu3(btc)2 (btc = benzene‐1,3,5‐tricarboxylate) directly within the open‐cell structure. Due to the creation of a microporous structure within a macroporous substrate, a material with a lung‐like porous structure is obtained (see picture: SEM micrograph of Cu3(btc)2 crystals in polyHIPE).

“…This monolith was a highly microcellar monolith called poly-HIPE (highly internal phase emulsion), based on styrene/ DVB emulsion polymerization with water phase dispersed in monomer matrix. The polyHIPE monolith with its surface modified by functional monomers via ATRP has been recently reported [71] for increasing the loading capacity. Some new investigation can be cited with regards to the polymer-based monolithic column based on a conventional free radical polymerization.…”

This review introduces to the readers our new perspectives of polymer-based monolithic column with a high performance for small solutes such as drug candidates, illustrating the fabrication of LC columns in capillary. First, we briefly reviewed the status quo of polymer-based monolithic columns, comparing with silica monoliths. The miniaturization of LC system with higher throughput (shorter analytical time) was stressed conceptually, along with a fine permeable bicontinuous monolithic structure with submicron domain size (skeletal thickness + pore size) for higher performance. Second, from these perspectives, our column preparation was described, while our specially designed porogenic solvents were introduced as a controller of the monolithic morphology via reaction-induced phase separation. Specifically, monolithic columns were exemplified in two polymer formats, that is, one monolith prepared by free radical polymerization of glycerin 1,3-dimethacrylate, GDMA, and the other prepared by stepwise polymerization of newly introduced multifunctional epoxy and diamino monomers. Both monolithic columns in capillary format demonstrated a fine bicontinuous structure, affording a good compatibility of the efficiency (H) and permeability (D). Especially, the epoxy-based column showed an excellent separation impedance, E (=H(2)/D). Our micro-HPLC data were discussed along with a prototyped wired chip device.
