摘要

<正>The hierarchical structure and interfacial morphology of injection-molded bars of polypropylene （PP） based blends and composites have been investigated in detail from the skin to the core. For preparation of injection-molded bars with high-level orientation and good interfacial adhesion

a dynamic packing injection molding technology was applied to exert oscillatory shear on the melts during solidification stage. Depending on incorporated component

interfacial adhesion and processing conditions

various oriented structure and morphology could be obtained. First

we will elucidate the epitaxial behavior between PP and high-density polyethylene occurring in practical molded processing. Then

the shear-induced transcrystalline structure will be the main focus for PP/fiber composites. At last

various oriented clay structures have been ascertained unambiguously in PP/organoclay nanocomposites along the thickness of molded bars.
