Morphology and mechanical properties of EPDM-graft-POSS nanocomposite obtained by reactive blending |
| 초록 |
Polyhedral oligomeric sisesquioxane(POSS)-graft-ethylene propylene diene terpolymer(EPDM) was prepared by reactive melt blending of maleated EPDM with amine functionalized POSS in an internal mixer, and their morphology, mechanical and dynamic mechanical properties were examined. Wide angle X-ray diffraction (WAXD) and transmission electron microscopy (TEM) results revealed that POSS formed nanocrystals and the POSS nanocrystals are dispersed uniformly in the rubber matrix. The POSS-g-EPDM exhibits a thermoplastic elastomer-like behavior. POSS nanocrystals and hydrogen bonded interactions between the amide acids formed from the reaction of maleic anhydride with amino group of the POSS is thought to induce physical crosslink points in this system. |
