Morphological Study of 10 MeV Electron Beam irradiated PE/EVA Blends

Cross-linking has been shown to dramatically improve the properties of polyethylene. In this work we examined the role of cross-linking on surface structure of polyethylene/ethylene-vinyl-acetate (PE/EVA) blends with different percentages. The specimens were prepared using Dr. Collin warm press system and irradiated under the 10 MeV electron beam in air at different absorbed doses. We observed by scanning electron microscope (SEM) that the morphology pattern of the blended sample after and before irradiation. It was concluded that the homogeneous pattern can be obtain in at least 30 percent of EVA in the blend and cross-linking make the pattern more homogeneous such a single polymer and only some micro voids can be seen in the pattern
