摘要
综述了通过活性自由基聚合如原子转移自由基聚合(ATRP)、氮氧稳定自由基聚合(NMP)、可逆加成断裂链转移聚合(RAFT)等方法合成含聚乙二醇(PEG)的嵌段共聚物的研究进展,并对含PEG类嵌段共聚物在溶液中的自组装技术和在药物载体、介孔材料以及碳纳米管中的应用进行了归纳,指出含PEG的嵌段共聚物可以自组装成多种形貌,直接影响材料的性能和应用,所以这些结构有潜在的应用价值和应用前景,并且合成新的含PEG的嵌段共聚物和开发具有新型结构、形貌可控的自组装体以及新的应用领域是今后的一个热点问题,具有重要的科学研究意义和实际应用价值。
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.
