Study of Morphology and Physical-Mechanical Properties of HDPE/PA6 and HDPE-g-MAH/PA6 Nanocomposites with Two Types of 30B and 15A Nanoparticles Prepared via Melt Compounding

Abstract

The nanocomposites of HDPE/PA6 and HDPE-g-MAH/PA6 in the presence of two types of 30B and 15A organoclays (Oclay) were prepared via melt compounding. The XRD and TEM results confirmed the nanoscale morphology obtained by the nanoparticles. HDPE-g-MAH/PA6 samples, due to the compatibility between the phases, indicated better morphology, higher viscosity and better barrier properties than HDPE/PA6 samples. In contrast, the presence of polyethylene led to the higher modulus, crystalinity and thermal stability of HDPE/PA6 samples. 15A nanoparticles caused better performance in the properties than other particles and specially a perceptible increase in the melt viscosity and barrier properties of HDPE-g-MAH/PA6 blend.
