摘要
多相高分子体系由不同聚合物组成,因其能够综合不同组分的性能特点,并且展现出一定的多相结构优势,在实际工业生产中已被广泛应用。多相高分子领域的研究热点之一是微观相形貌结构与材料宏观流变行为和机械性能之间的关系,尤其考虑到相间界面性质对多相体系结构-性能调控具有重要意义,近年来多相高分子体系的界面流变行为研究也备受关注。本文总结了该方向的最新研究进展,首先阐述包括界面滑移、扩散、反应和增容等常见界面现象及其宏观流变行为特征,其次介绍界面流变性能的表征方法,如直接测量、流变模型预测和多层结构间接测量等,最后强调界面流变在多相体系结构-性能调控中的重要性,特别是在共混体系形貌稳定、相转变和多层共挤出界面流动稳定等方面的应用,并对界面流变研究面临的挑战和未来趋势进行展望。
Multiphase polymeric systems composed of different polymers have gained broad applications in practical industry because they can combine characteristic performances of the different components along with some specific advantages of multiphase structure.One topic of great research interest in the field lies in the relationship between the microstructure and the macroscopic rheological/mechanical properties of multiphase polymeric systems.In particular,considering the importance of interface for the structure-property regulation of multiphase systems,study of interfacial rheological behavior in multiphase polymeric systems has also attracted much attention in recent years.This review aims to summarizing the latest advancements in this research area.First,the commonly involved interfacial phenomena including interfacial slip,interdiffusion,reaction,and compatibilization,along with their corresponding rheological characteristics,will be introduced.Next,the methods of interfacial rheology characterization,including direct measurements,rheological model predictions,and indirect measurements based on multilayer structures,will be depicted.Finally,the importance of interfacial rheology in regulating the structure-property relation of multiphase systems will be highlighted,particularly shedding light into the morphological stabilization and phase transitions in blend systems as well as the interfacial flow stabilization in multilayer co-extrusion.The review will be ended with a perspective on the existing challenges and a prospect on the future trends.
