嵌段共聚物自组装中聚合诱导自组装方法的研究进展

Progress in the self-assembly of block copolymers of polymerizationinduced self-assembly

综述了一种嵌段聚合物纳米微球的制备新方法——聚合诱导自组装(PISA)方法,该方法结合了活性聚合和自组装两个概念,可控制嵌段聚合物纳米微球的大小、形貌和表面性能,讨论了PISA方法的优势和缺陷,并展望了PISA方法的未来发展方向。

A new method of preparing block copolymer nanoparticles,the polymerization-induced self-assembly（PISA） method is described. The PISA method combines the concept of controlled radical polymerization and the self-assembly of block copolymer,which is recognized as an efficient route to produce block copolymer nanoparticles of controlled size,morphology,and surface chemistry. We discussed the advantages and drawbacks of PISA method,as well as the future research direction.
