Experimental Study and Modeling of Flow Behavior and Orientation Kinetics of Layered Silicate/Polypropylene Nanocomposites in Start-Up of Shear Flows

摘要

The effects of organoclay contents on the start-up flow properties of layered nano-scale particles in the simple shear mode were investigated. The addition of small amounts of nanoclays to PP melts was found dramatically to change the flow characteristics and to create stress overshoots at large shear rates.
