丙烯腈嵌段共聚物的合成及其自组装研究进展

Research progresss of synthesis and self-assembly for acrylonitrile block copolymers

综述了含聚丙烯腈(PAN)嵌段共聚物的合成方法及其在溶液中的自组装技术。对常用的活性自由基聚合方法,如原子转移自由基聚合(ATRP)、可逆加成断裂链转移(RAFT)聚合、氮氧自由基聚合(NMP)以及钴调介自由基聚合(CMRP)等方面的研究进行了总结,同时对PAN类嵌段共聚物在溶液中的自组装技术进行了概括。最后提出了现有技术存在的问题,并对其今后发展方向进行了展望。

The synthetic processes for block copolymers with polyacrylonitrile（PAN） and their self-assembly in solution were reviewed. Mainly some common radical polymerization methods,including ATRP（atom transfer radical polymerization ）, RAFT （reversible addition-fragmentation chain transfer） polymerization, NMP （nitroxide radical polymerization）, CMRP（cobah-mediated radical polymerization） and so on,were overviewed. Meanwhile, self-assembly of PAN block copolymers in solution was also summarized. Finally,some existent technic problems in these two aspects were proposed,and their future development direction was expected.
