Abstrak

We investigated the impact of silica nanoparticles on the complex shear moduli and molecular dynamics of elastomeric nano-composites formed from ethylene propylene diene monomer (EPDM) and polypropylene (PP). The blended system was composed of immiscible amorphous/semi-crystalline polymers. The complex shear moduli of the EPDM/PP/SiO2 nano-composites and their corresponding neat filler blends were measured at different shear rates in the temperature window − 95–50 °C. The impacts of filler on the stress–strain and thermal behaviors were also investigated. The nano-composites exhibited higher shear moduli than the corresponding neat polymer blends. This trend was linked to the hindered glass-relaxation dynamics of the EPDM polymer in the nano-composites.
