摘 要: 介绍了原子转移自由基聚合法(ATRP)制备聚合物刷(平面刷、球形刷和分子刷)的研究进展及应用前景。聚合物刷子的奇异构象使其具有许多新奇的性质和潜在的应用前景。ATRP 是制备具有可控结构的聚合物以及有机/无机杂化材料的一种较好的方法。通过 ATRP 制备聚合物刷,可以有效地改变聚合物刷的组成和聚合度,从而改变聚合物刷的表面性质,设计出具有新型结构及性能的材料。 Atom transfer radical polymerization(ATRP)is a robust method for the prparation of well-defined (co)polymers.This process also enables the preparation of a wide range of polymer brushes where(co)polymers are covalently attached to either curved or flat surfaces.In this review,the general methodology for the synthesis of poly- mer brushes from surfaces,polymers and colloids is summarized focusing on reports using ATRP.In the end,the characteristics and applications of polymers brushes are briefly introduced.
