An investigation of mechanical properties and breakdown strength of polypropylene/ultra-high molecular weight polyethylene nanocomposites
An investigation of mechanical properties and breakdown strength of polypropylene/ultra-high molecular weight polyethylene nanocomposites
This work studies the effects of surface-modified magnesium oxide (MgO) nanofiller on the mechanical properties and AC breakdown strength of polypropylene (PP) and ultra-high molecular weight polyethylene (UHMWPE) composites. The inclusion of nanoparticles results in improved interfacial interactions as a consequence of the transition from separate crystallization to co-crystallization. Thus, nano-MgO enhances the breakdown strength of PP/UHMWPE by acting as a compatibilizer between the PP/UHMWPE. UHMWPE decreases Young’s modulus and ultimate tensile strength while increasing elongation at yield point in the PP matrix. PP/UHMWPE has increased elasticity due to weak interfacial adhesion. The addition of nano-MgO, however, promotes stronger bonding between PP and UHMWPE phases, providing stiffer composites than those without MgO. There are no apparent differences between PP/UHMWPE and PP/UHMWPE/MgO regarding ultimate tensile strength. It is obvious that the dielectric breakdown strength and elastic enhancement are significantly influenced by the interfacial adhesion between the polymers.

Abstract
This work studies the effects of surface-modified magnesium oxide (MgO) nanofiller on the mechanical properties and AC breakdown strength of polypropylene (PP) and ultra-high molecular weight polyethylene (UHMWPE) composites. The inclusion of nanoparticles results in improved interfacial interactions as a consequence of the transition from separate crystallization to co-crystallization. Thus, nano-MgO enhances the breakdown strength of PP/UHMWPE by acting as a compatibilizer between the PP/UHMWPE. UHMWPE decreases Young’s modulus and ultimate tensile strength while increasing elongation at yield point in the PP matrix. PP/UHMWPE has increased elasticity due to weak interfacial adhesion. The addition of nano-MgO, however, promotes stronger bonding between PP and UHMWPE phases, providing stiffer composites than those without MgO. There are no apparent differences between PP/UHMWPE and PP/UHMWPE/MgO regarding ultimate tensile strength. It is obvious that the dielectric breakdown strength and elastic enhancement are significantly influenced by the interfacial adhesion between the polymers.
