Characterization of Nanoparticles Fe3O4 Nanocomposite Blend with Thermoplastic HDPE

Abstract

This study aims to determine the mechanical properties, morphology and thermal thermoplastic blends of High Density Polyethylene (HDPE) with a filler material Fe₃O₄ nanoparticles. The method is performed by mixing the ingredients on Internal Mixer tool types Labo Plastomill 30 R I50 models with variations in  the quantity (2,4,6,8) wt% Fe₃O₄ nanoparticles with a size of 33.11 nm and 2% by weight Polyethylene Grafted Maleic Anhidride (PE -g-MA) and without PE-g-MA, with a chamber volume of 60 cc with a temperature of 150⁰C at a speed of 50 rpm for 10 minutes. The results of the mechanical properties obtained  an increase in tensile strength maximum with increasing the quantity of nanoparticles Fe₃O₄ without and the compatibilizer PE-g-MA with optimal the quantity at 2% by weight, while the elongation at break decreased with increasing the quantity of nanoparticles Fe₃O₄, but the tensile strength better by using compatibilizer, as well as Young's Modulus, s increased with increasing magnetic nano particles, but in general without compatibilizer better. The results of the dispersion morphology of the occurrence of a homogeneous mixture and intercalates between HDPE thermoplastic matrix with Fe₃O₄ particles and homogeneous mixture. The addition amount of filler increases the thermal stability and crystallinity of composite.
