摘      要：Nanogels hold promise as soft and functional carriers and nanoreactors,but whether they will ever reach the stage of large-scale application depends crucially on efficient production methods,and on what interesting properties and functionalities they can *** particular,nanogels consisting of highly charged polyelectrolyte have not yet been very much ***,the authors present a novel and generic strategy for controlled and efficient synthesis of a large diversity of polyelectrolyte *** method is based on polymerizing an ionic monomer in the presence of an oppositely charged polyion-neutral diblock copolymer as template,while adding a *** growing polymer chains assemble with the template,forming polyion complex micelles,which dissociate upon increasing salt *** separation yields nanogels with well-controlled size and properties,and free template polymers that can be used *** design can be applied generally to a wide range of both cationic and anionic monomers,as well as various ***-up production presents no problems as increasing monomer concentration(hundreds of mM)and reaction volume(up to 1 L)hardly compromise product ***,the obtained nanogels with their well-controlled size,morphology,chemistry,and cross-linking degree perform well as soft nanocarriers and catalytic nanoreactors.
