摘要：

This Study investigates the effect of multiwalled carbon nanotube (MWCNT) content on the rheological and dynamic mechanical properties of polypropylene (PP). Various melt indices of polypropylene were blended with different MWCNT contents. Melt flow index (MFI), melt viscosities and dynamic mechanical properties were measured. Results indicate that melt flow index of MWCNT/PP was decreased with the increasing of MWCNT content. The melt viscosities of MWCNT/PP increased with MWCNT contentat the shear rate ranges of 100 similar to 10,000 s(-1) which were simulated to the extrusion and injection molding process. The storage modulus and tan delta of the composites were also investigated. (C) 2008 Elsevier Ltd. All rights reserved.
