Rheology of Particulate-Filled Polymers, Nanocomposites, and Fiber-Reinforced Thermoplastic Composites

Rheology of Particulate-Filled Polymers, Nanocomposites, and Fiber-Reinforced Thermoplastic Composites 

it is well established that, in general, the addition of fillers to a molten polymer increases the melt viscosity and decreases the melt elasticity. The volume fraction of the particles as well as other factors, such as the shape of the particles, the particle size and size distribution, and the state of dispersion of the particles (well-dispersed state or agglomerated state), are known to influence the bulk rheological properties of particulate-filled polymer melts.
