“…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.…”
