Abstract:

The ionic liquids as a new class of green solvent have received the majority attention. In this study, two polymeric ionic liquid monomers were synthesized by one step method, and polymerized by precipitation polymerization method. The resultant materials were characterized by nuclear magnetic resonance spectroscopy (1H NMR), scanning electron microscopy (SEM) and thermo gravimetric analyzer (TGA) methods. The results showed that the morphology of the resultant materials was ellipsoidal particles with the size of about 600 nm. The adsorption properties of the resultant materials for bovine serum albumin (BSA), ovalbumin (OVA), bovine hemoglobin (BHb), lysozyme (Lys) and trypsin (Try) were also evaluated. The two poly(ionic liquid)s materials showed excellent adsorption properties for proteins. The poly(4-vinyl benzyl chloride quaternary ammonium ionic liquid)s material exhibited the best adsorption to trypsin. Such materials show potential in biomedical and material engineering.

Key words: ionic liquids, poly(ionic liquid)s materials, proteins, quaternary ammonium
