Abstract:

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.
