| Abstract: | Poly(ethylene-co-vinylacetate)/sodium montmorillonite (EVA/MMT) and Poly (ethylene-co-vinylacetate)/arganophilic montmorillonite (EVA/o-MMT) nanocomposite were prepared by solid-state mixing. The morphology and structure of the composites were explored by scanning electron microscopy (SEM),wide-angle X-ray diffraction (WAXD ), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA).The results showed that the intercalated nanocomposite was successfully synthesized for EVA/o-MMT system, while in the EVA/MMT nanocomposite, MMT were poorly dispersed in the order of urn. An unexpected rubbery plateau modulus of EVA/o-MMT nanocomposite above melting point of EVA was explored by DMA. The possible origins of this high-temperature modulus were analyzed. |
