摘要

颗粒填充聚合物(包括聚合物纳米复合材料) 熔体通常表现出模量升高、频率依赖性的改变以及高含量填充体系的屈服行为等与单纯聚合物明显不同的流变行为

并且这些流变特性还会受到填料含量、形状尺寸以及颗粒-聚合物之间相互作用等诸多因素的影响。填充聚合物的宏观流变行为是与其微观结构的形成和演化以及高分子链在特定条件下的阻尼松弛过程密切联系在一起的。本文综述了颗粒填充聚合物(包括聚合物纳米复合材料) 在力场作用下的流变特性以及各种因素对其流变行为的影响

尤其是着重阐述了聚合物纳米复合材料的流变松弛机理和基于热力学理论建立起来的、描述填充体系熔体流变行为的Leonov 模型。

Abstract

Particle-filled polymers(including polymer-based nanocomoposites) usually exhibit higher moduli

variation in frequency dependence and the yield behavior of concentrated filled systems

which is distinctly different from the Rheology of plain polymers.Furthermore

these rheological characteristics could be influenced by many factors such as the filler' s loading

shape

size

and the interaction between particles and polymers.The rheological behavior of filled-polymers is closely associated with the formation and evolution of microstructure involved in materials as well as the damped relaxation processes under specific conditions.In this paper

the rheological characteristics of filled polymers(including polymer-based nanocomposites) under the force field and various influencing factors acted on them were reviewed

especially elucidating the rheological mechanism of polymer-based nanocomposites and Leonov model used to describe rheological behaviors of filled polymers.
