Improvement in Dispersion of Mwcnts into Epdm

International Polymer Science and Technology, 2009
In this study, we examined the improvement in dispersion of multi-walled carbon nanotubes (MWCNTs) into ethylene-propylene-diene rubber (EPDM). The dispersion of MWCNTs was observed by an optical microscope and a scanning electron microscope. Normally, MWCNTs were hardly dispersed into non-polar EPDM matrix, and large agglomerates of MWCNTs were ...
