摘要：

The linear viscoelastic behavior of the isotactic polypropylene/carbon black composite melt in which the filler particles can aggregate and form a filler network is investigated. With a higher filler loading the enhancement effect of the filler particles on the composite melt becomes more significant, which can be explained by the filler-polymer interaction and the hydrodynamic effect. When the filler network appears in the composite melt, the storage modulus exhibits another increasing mode, revealing that the percolating filler network has an additional enhancement effect on the composite melt. This is explained in a microscopic view of point with the consideration of the polymer shells on the filler particles.
