Biocompatible mesoporous polymeric ionic liquid with high adsorption capacity for selective isolation of ovalbumin

Ionic liquids are becoming widely applied in the extraction/separation of biological molecules. In this study, the solidification of ionic liquid 1-hydroxyethyl-3-vinylimidazole chloride ([HVIM]Cl) was achieved via one-pot free radical copolymerisation with divinylbenzene (DVB) as a cross-linking reagent, giving a mesoporous hydrophilic polymeric ionic liquid (PIL). Mesoporous PIL possesses a large surface area of 328.32 m2·g−1 and a high pore...
