Morphology and mechanical properties of low density Polyethylene/Multi-Walled carbon nanotubes nanocomposites

Abstract

Low density polyethylene/multi-walled carbon nanotubes (LDPE/MWNTs) nanocomposites were manufactured with screw extrusion and injection moulding. The morphology and mechanical properties of LDPE/MWNTs nanocomposites were investigated. The results show that, at low content of MWNTs, they could uniformly disperse into LDPE and contribute to the crystallization of LDPE; LDPE crystal maintains the original structure in the nanocomposites; compared to LDPE, the increases in tensile strength and Young’s modulus for LDPE/3.0 wt.% MWNTs nanocomposite can be up to 27 % and 148 %, respectively.
