One-step synthesis of thermosensitive nanogels based on highly cross-linked poly(ionic liquid)s

Abstract

A gel for all seasons: Thermosensitive nanogels based on highly cross-linked poly(ionic liquid)s (CLPNs) were prepared in one step by the copolymerization of imidazolium-based monomers with cross-linkers in selective solvents. Reversible nanogel-macrogel transitions of CLPNs in methanol could be achieved by changing the temperature.
