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 ex- ponential 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 under- standing 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.

复杂单链的形状特征和指数法聚合

作为聚合物科学的重要组成部分，聚合物溶液中的单链构象和聚集结构已被许多经验指数定律广泛研究。综述中总结了几种常用的指数规律，并介绍了在复杂单链和聚集体形状特征研究中的应用。薄膜的聚集结构和形貌可以通过前驱体溶液来控制，因此深入了解前驱体溶液的内在特性就显得尤为重要。结合电子显微镜、光谱等，可以利用指数规律进一步研究聚合物溶液中各层级结构单元的单链、聚集体大小和形貌、结构演化以及运动过程的规律，
