Abstract

JIN-HUA, Tai; GUO-QIN, Liu; HUANG, Caiyi  and  LIN-JIAN, Shangguan. Mechanical properties and thermal behaviour of LLDPE/MWNTs nanocomposites. Mat. Res. [online]. 2012, vol.15, n.6, pp. 1050-1056.  Epub Oct 02, 2012. ISSN 1516-1439.  http://dx.doi.org/10.1590/S1516-14392012005000122.

Multi-walled carbon nanotubes (MWNTs) were incorporated into a linear low-density polyethylene (LLDPE) matrix through using screw extrusion and injection technique. The effect of different weight percent loadings of MWNTs on the morphology, mechanical, and thermal of LLDPE/MWNTs nanocomposite had been investigated. It was found that, at low concentration of MWNTs, it could uniformly disperse into a linear low-density polyethylene matrix and provide LLDPE/MWNTs nanocomposites much improved mechanical properties. Thermal analysis showed that a clear improvement of thermal stability for LLDPE/MWNTs nanocomposites increased with increasing MWNTs content.

Keywords : LLDPE; MWNTs; mechanical properties; thermal behavior.
