Preparation and Properties of Ethylene Propylene Diene Rubber/SiO₂/Carbon Nanotubes Composites

Abstract:

This paper studies how the addition of Carbon nanotubes (CNT) influencing the properties, especially the mechanical properties and colorimetry of ethylene propylene diene rubber (EPDM)/SiO₂ composites. The results show that the increased content of CNT can turn EPDM/SiO₂ composites from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/SiO₂ composites would be acceptable when the CNT content is below 3%. When the CNTs content reaches 4%, the tensile strength of EPDM is the maximum.
