Electrical and Mechanical Properties of PA66/PPE Blend Containing MWCNT

Abstract

Polyamide 66 (PA66)/poly(2,6-dimethyl-4,4-phenylene ether) (PPE) blends containing multi-walled carbon nanotube (MWCNT) were prepared. PPE-L and PPE-H having different melt viscosity were used. During blending, 3 phr of styrene-ethylene-butadiene-styrene (SEBS) as an impact modifier and 2 phr of MWCNT were added. The PA66/PPE (80/20) and (60/40) blends were considerable in teens of the electrical and mechanical properties. The mechanical properties of PA66/PPE-L (80/20) blends were increased up to 2 phr MWCNT and decreased at the higher composition of MWCNT due to the aggregation of MWCNT. The surface resistivity of PA66/PPE-L (80/20) blends was decreased with the MWCNT composition, and showed the percolation threshold at 2 phr MWCNT.
