受限条件下不相容聚合物共混物的形态演变研究进展

Morphology of Immiscible Polymer Blends in Confined Shear Flow

不相容聚合物共混物形成的相结构决定着共混材料的各项性能。近几年,研究发现不相容聚合物共混物受限条件下的相结构与非受限条件下的相结构有很大不同。本文从理论模型、实验结果以及影响因素(包括受限程度、组分比、剪切速率和粘弹性)等方面,综述了近年来开展的受限条件对不相容聚合物共混物相结构影响的研究进展,指出了现有研究的一些不足之处并展望了该领域的发展趋势。

The performances of practical multiphase materials made from immiscible polymer blends are usually determined by the microscopic phase structures of blends.Recently,it has been demonstrated that the morphologies of confined multiphase polymer blends differ significantly from those observed in the bulk systems,especially in shear flow.In this paper,the recent researches on the morphology evolution of immiscible polymer blends in confined condition are reviewed.Theoretical models together with experimental re...
