| 英文摘要 | Polycarbonate (pc) was melt blended with small amount of liquid-crystalline polymer (lcp) and various contents of glass beads (gb) having different diameters. the rheological measurements indicated that the gb addition increased the viscosity ratio and seemed unfavorable to the lcp fibrillation. however, the morphological observation showed that the lcp fibrillation was promoted by the gb addition and varied with the gb packing. with the increased gb packing by increasing the gb content and/or decreasing the gb diameter, lcp deformed from spheres and ellipsoids into stretched ellipsoids at lower shear rates and into long fibrils at higher shear rates. although higher content of smaller gb jammed into the larger lcp droplets and inhibited the lcp fibrillation, very long lcp fibrils formed at higher shear rates at a high enough packing of gb. the relationship between gb packing and lcp fibrillation revealed two kinds of hydrodynamic effects of gb promoting the lcp fibrillation: at lower gb packing, the shear flow was enhanced by the high local shear between gb, in quantity; and for a high enough gb packing, the shear flow was changed, in quality, into elongational flow, which was more effective for the lcp fibrillation.
