摘要
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。
.Rheology of particle filled polymer （PFP） melts is one of the most important subjects in polymer science. PFP melts exhibit diverse complicated theological phenomena depending on the structure of filler particles, the chemical nature of the polymeric matrix and the interracial interaction. However, there are also some universal and general rheological rules among diverse experimental systems. The main experimental phenomena and results from theoretical （model） studies involved in dynamic rheology of PFP melts are summarized in this paper. The common views achieved and the scientific controversies remained so far are pointed out after heavily analyzing extensive investigations on the liquid-to- solid transition of PFP melts, the molecular relaxations, the so-called ＂zero shear rate＂ viscosity and ＂equilibrium＂ shear modulus, the time-concentration superposition principles, the two-phase model and the nonlinear viscoelasticity. Some perspectives on further studies on rheology of PFP melts are given.
