In this article we review the recent polymer literature where dielectric spectroscopy has been used to investigate the segmental dynamics of polymers under the constraints produced by self-structuring. Specifically, we consider three cases: (i) semicrystalline polymers, (ii) segregated block-copolymers, and (iii) asymmetric miscible polymer blends. In these three situations the characteristics of the dielectric relaxation associated with the polymer segmental dynamics are markedly affected by the constraints imposed by the corresponding structural features. After reviewing in detail each of the polymer systems, the most common aspects are discussed in the context of the use of dielectric relaxation as a sensitive tool for analyzing structural features in nanostructured polymer systems.
本文综述了近年来利用介电谱研究在自结构化产生的约束下聚合物链段动力学的高分子文献。具体而言，我们考虑了三种情况：（i）半结晶聚合物，（ii）相分离的嵌段共聚物，以及（iii）不对称互容聚合物共混物。在这三种情况下，与聚合物链段动力学相关的介电弛豫特征明显受到相应结构特征所产生的约束的影响。在详细回顾了每种聚合物体系之后，我们将在分析纳米结构化聚合物体系结构特征时将介电弛豫作为一种敏感工具的使用方面讨论最常见的方面。
