Block copolymers can self-assemble into a variety of shaped nanoparticles and ordered nanomaterials either in solution or in bulk

which has great potential applications in areas of nanomaterial and nanotechnology.For further development of these areas

functionalization of the self-assembled nanoparticles was eagerly wanted.To mediate the structures

shapes and functions of these nanoparticles

well-defined functional block copolymers for self-assembly need to be synthesized with controlled polymerization.In this review

development on self-assembly of block copolymers is summarized based on related research progress in this group.Reactive block copolymers were synthesized by controlled radical polymerization first

then shaped core-shell polymer nanoparticles were prepared by self-assembly of reactive block copolymers either in solution or in bulk.After chemical or physical crosslinking

the morphologies of the nanoparticles can be fixed and then novel methods for preparation of core-shell polymer nanoparticless were obtained.
