摘要
The linear dynamic rheology for a series of filled polymer melts is investigated to take account for the respective contributions of the bulky polymer phase away from the filler inclusions and the "filler phase" composed of filler particles coated with polymer layer. Time-concentration superposition principles are introduced to the linear viscoelasticities of both the bulky polymer phase and the "filler phase". The result highlights the importance of the polymer dynamics to both the "filler phase" and the composite melt. Polymer mediated filler jamming towards glass formation is revealed for the "filler phase", which accounts for origin of the fluid-to-solid transition upon filling.
