Polymerised high internal phase emulsions for fluid separation applications

Development of high internal phase emulsion polymeric monoliths for highly efficient enrichment of trace polycyclic aromatic hydrocarbons from large-volume water samples

“…The external phase is converted into a solid polymer and the emulsion droplets are removed yielding (in most cases) a highly interconnected network of micron sized pores of quite well defined diameter [12]. The resultant polyHIPEs possessed two distinct types of pore: the droplet-templated pores as 'voids' and the interconnecting holes as "windows", which make them as ideal adsorbent materials for protein purification [15,16], water purification [17,18], gas capture [19], and other sorption applications [20]. In addition, besides the inherent porous characteristics and highly interconnected networks, monolithic polyHIPE columns exhibited better mechanical properties and much more convenient for miniaturized and automated sample preparation compared with conventional particulate materials, and have been used to successfully capture alkylbenzenes [21], heavy metals [22], and proteins [23,24] with high binding capacity.…”

Highly permeable macroporous polymers via controlled agitation of emulsion templates

“…Emulsion templated macroporous polymers can be produced from many different monomers, which allows tailoring of properties such as compression and tensile properties [8,9]. This might enable polyHIPEs to find potential applications in many fields [10], for example since a polyHIPE's structure is similar to that of bone they have been explored for as scaffolds for tissue engineering applications [11][12][13][14]. They are also explored for potential applications in the energy sector in such varied roles as storage of hydrogen and methane clathrates [15,16], downwell filters in oil wells [7] or a polymer cement hybrids [17].…”

“…Furthermore, polyHIPEs have also been explored for use in chromatography [18] and ion exchange columns [19] and in flow through chemistry for example as amine scavengers [10,20,21].…”

High-internal-phase-emulsion polymeric monolith coupled with liquid chromatography–electrospray tandem mass spectrometry for enrichment and sensitive detection of trace cytokinins in plant samples

“…Because of their unique structure, HIPEs are particularly useful as templates for the construction of highly porous and permeable polymeric materials with a well-defined porosity [4][5][6]. The resulting materials are often termed a polymerized HIPE or polyHIPE and are suitable for a wide variety of applications, including tissue engineering and cell culture scaffolds [3,7,8], pure protein scaffolds [9,10], enzyme immobilization [11,12], water purification [3,13], fluid separation [14], CO 2 capture [15], hydrogen storage [3], and sensor Electronic supplementary material The online version of this article (doi:10.1007/s00216-015-8782-3) contains supplementary material, which is available to authorized users. materials [3,16], because of their readily controllable pore and pore-throat size, ease of functionalization, and flexible synthesis.…”
