【Abstract】 In the past decades,considerable interests have been devoted to fabricating stimuli-responsive polymers(SRP) due to their prospective applications in the field of smart materials,biomedical,catalysis,sensors,and so on.More recently,we have demonstrated a facile synthesis strategy to prepare poly(ionic liquid)s(PIL)-based nanogels via the conventional radical copolymerization of IL-based monomers and the cross-linkers ethylene glycol dimethacrylate(EGDMA) and divinylbenzene(DVB) in selective solvents.Herein,we reported on a novel redox-sensitive nanogel prepared via the cross-linking copolymerization of ionic liquid monomer with the cross-linker containing a disulfide bond in selective solvent.The results demonstrated that the highly cross-linked PIL-based nanoparticles could be easily obtained through this approach.And the as-prepared nanogels could undergo redox-responsive behavior due to the introducing of the cross-linker with a disulfide bond.The stimuli-responsive performance of PIL-based nanogel was characterized by dynamic light scattering(DLS).And the nanogels were characterized using NMR,FTIR,TEM,SEM and TG.Additionally,using Rhodamine B(RB) as a model drug,the performance on controlled release of the as-prepared nanogel was investigated.The results illustrated that the controlled release of RB could be accomplished in the presence of reductive environment(DTT,GSH).更多还原
