粒子填充高分子(Particle filled polymers,PFP)熔体流变行为是高分子科学的重要研究课题之一。PFP流变表现复杂,因粒子结构、基体化学性质、界面相互作用而异,但也具有一些普适的、一般的流变学规律。本文从PFP熔体类液-类固转变、分子弛豫特性、“零剪切”黏度与“平衡”模量、时间-浓度叠加原理、两相模型、非线性黏弹行为等6个不同角度系统介绍PFP动态流变行为的主要实验现象和理论(模型)研究结果,分析该领域已取得的研究共识和尚存的学术争议,并展望该领域今后的研究方向。
Particle filled polymers (PFP) melt rheological behavior is one of the important research topics in polymer science. The rheological behavior of PFP is complex and varies depending on the particle structure, the chemical properties of the matrix and the interfacial interactions, but it also has some general and general rheological laws. In this paper, the liquid-solid transition of PFP, the molecular relaxation, the “zero shear” viscosity and the “equilibrium” modulus, the superposition principle of time and concentration, the two-phase model, the nonlinear viscoelastic behavior and so on Six different perspectives are used to introduce the main experimental phenomena and theoretical (model) research results of dynamic rheological behavior of PFP. The research consensus and remaining academic controversies have been analyzed in this field and the future research directions in this field are expected.
