Article Synopsis
  • Hybrid polypropylene (PP) composites reinforced with graphene nanoplatelets (GnPs) and glass fiber (GF) showed improved mechanical performance due to synergistic effects from the combined reinforcements.
  • An optimal concentration of 0.5 wt % GnP led to significant improvements in tensile strength (52% increase) and flexural strength (39% increase), along with enhanced thermal conductivity (68%) due to better crystallinity in the PP matrix.
  • These findings suggest that leveraging hybrid composites can allow for tailored properties suitable for high-performance industrial applications, addressing the need for stronger, lighter, and thermally conductive materials.

In this work, hollow fiber porous nanocomposite membranes were successfully prepared by the incorporation of a porous nanoparticle (zeolite 5A) into a blend of linear low-density polyethylene (LLDPE)/low-density polyethylene (LDPE) combined with azodicarbonamide as a chemical blowing agent (CBA). Processing was performed via continuous extrusion using a twin-screw extruder coupled with a calendaring system. The process was firstly optimized in terms of extrusion and post-extrusion conditions, as well as formulation to obtain a good cellular structure (uniform cell size distribution and high cell density).
