Effects of Electron Beam Irradiation on Mechanical Properties of PP/EPDM Nanocomposites

摘要

Nanocomposites are materials created by introducing nanoparticulates commonly referred to as a filler into the matrix. Blends of polypropylene (PP)/ethylene propylene diene monomer (EPDM)/montmorillonite (MMT) were treated by compatibiliser maleic anhydride polypropylene (MAPP) and irradiated using an electron beam. The effects on mechanical properties for both samples were compared with the untreated nanocomposites. The effects of montmorillonite clay loading on mechanical properties of PP/EPDM/MMT were investigated. The d-spacings of the clay in nanocomposites were examined using x-ray diffraction (XRD) and the extent of delamination was observed by a transmission electron microscope (TEM).
