Research progress of synthesis and self-assembly for poly(ethylene glycol)-containing block copolymers

Research progress of radical polymerization methods for block copolymers with poly(ethylene glycol) is reviewed in this paper，including ATRP (atom transfer radical polymerization)，NMP (nitroxide-mediated radical polymerization)，and RAFT (reversible addition-fragmentation chain transfer polymerization). Meanwhile，self-assembly in solution and applications of PEG-containing block copolymers in drug carriers，mesoporous materials and carbon nanotubes are also summarized. PEG-containing block copolymers can self-assemble into a variety of morphology of structures，which will directly affect the performance and application of the materials，so these structures have potential value and application prospects. The synthesis of new PEG-containing block copolymers and development of new，morphology-controlled self-assembly structures and new applications will be a central issue in the future with important scientific significance and practical value.
