Abstract
AbstractIsotactic polypropylene/ultrahigh-molecular-weight polyethylene blends (iPP/UHMWPE) and iPP/carbon nanotubes composites (iPP/CNTs) were prepared by a coagulation method followed by compression molding. The percolation thresholds for melts of iPP/UHMWPE blends and iPP/CNTs composites determined by rheometer, were beyond 5.0 wt% and close to 4.0 wt%, respectively. The creep and creep-recovery behavior of iPP/UHMWPE and iPP/CNTs melts were systematically investigated by rheological measurements. The results indicated that UHMWPE and CNTs played similar roles in the material’s elastic recovery, the addition of 2.0 wt% UHMWPE or 0.2 wt% CNTs increased the elastic recovery about 10 fold in comparison with neat iPP.
