摘　　要：高分子纳米复合材料(PNCs)以其优异的机械性能和多功能性等特点,在众多领域展现出巨大的应用潜力和发展前景。但是,由于对PNCs受限动力学和流变学缺乏充分理解,PNCs同时也存在性能调控难度大和加工制备技术不成熟等不足。本文旨在总结近年来PNCs在受限动力学与流变学方面的最新研究进展,从多尺度分子动力学与流变学、多尺度粒子动力学与流变学两方面阐述PNCs中受限动力学与线性流变学的关系,探讨其研究方法、理论基础以及未来发展方向。Polymer nanocomposites(PNCs)have demonstrated significant potential and promising development prospects in numerous fields,owing to their exceptional mechanical properties and multifunctionality.However,the inadequate understanding of the confined dynamics and rheology of PNCs poses challenges in manipulating their properties and results in immature processing and preparation technologies.This monograph aims to summarize the recent advancements in the confined dynamics and rheology of PNCs and explain the relationship between confined dynamics,including multiscale molecular dynamics and multiscale particle dynamics,with linear rheology in PNCs.It also discusses the research methods,theoretical foundations,and future directions.
