This paper studies how the addition and various content of Carbon nanotube (CNT) affecting the properties, especially the color difference of ethylene propylene diene rubber (EPDM)/ CaCO 3 composites. The results show that the increased content of CNT can turn EPDM/CaCO 3 composites from lighter, greener, and bluer to darker, redder and yellower, respectively.

Abstract

This paper studies how the addition and various content of Carbon nanotube (CNT) affecting the properties, especially the color difference of ethylene propylene diene rubber (EPDM)/ CaCO 3 composites. The results show that the increased content of CNT can turn EPDM/CaCO 3 composites from lighter, greener, and bluer to darker, redder and yellower, respectively. The total color change (ΔE) of EPDM/CaCO 3 composites is acceptable, when the content of CNT is less than 2wt%. The optimum tensile strength of EPDM composites can be gained, when the content of CNT is 3%.

Key findings
