Morphology and Rheological Behavior of COC/EBC/CNT Hybrid Nanocomposites

In this work the morphology and rheological behavior of cyclic olefin copolymer/Ethylene 1-Butene copolymer blends in the presence of multi wall carbon nanotubes (MWCNTs) was studied. The blend samples of COC/EBC (80:20) with sea island morphology detected by FESEM images were inspected. The effect of feeding sequence on localization of CNT was also investigated. The rheological results showed that the feeding sequence could not play a significant role in determining the CNTs localization and the major part of nanotubes located in the COC phase. This was in agreement with theoretical calculation results. The FESEM micrographs also revealed appropriate dispersion of nanotubes and confirmed the rheological measurements results.
