摘　　要：高分子在溶液中的单链构象和聚集态结构是高分子科学的重要内容,在研究中往往应用到许多指数经验规律.总结了几种通常用来研究高分子溶液的指数律方法,并介绍了指数律如何应用于复杂高分子单链及聚集态结构的形状特点研究.通过前体溶液的调控实现对薄膜凝聚态结构以及形貌的操纵是一种新思路、新方法.因此,深刻认识高分子在前体溶液中的本征性质尤为重要.通过指数律研究,结合电镜、光谱等方法,可深入研究高分子溶液单链、聚集尺寸及形态结构演变与各层次结构单元的运动过程及规律,为高分子材料的分子设计、功能开发及应用奠定理论基础.Being an important part of polymer science, the single chain conformation and aggregation structure in polymer solution has been widely studied by many experiential exponential laws. In the review, several kinds of commonly used exponential laws were summarized, and the use in the study of shape characteristics of complex single chain and aggregation was introduced. The aggregation structure and morphology of films can be controlled by precursor solution, so deep understanding to the intrinsic properties of precursor solution is particularly important. Combined with the electron microscope, spectra, etc., the exponential law can be used to further study the single chain, aggregation size and morphology, structure evolution, and the law of the movement process of structure units at all levels in polymer solution, this will lay a theoretical foundation for the molecular designing, functional development and application of polymer materials.
