Ethylene-vinylene acetate copolymer (EVA), carboxyl nitrile-butadiene rubber (XNBR), dicumyl peroxide, and carbon nanotubes (CNT) were applied to fabricate the EVA/XNBR/CNT composites, in which the mixing ratio of EVA/XNBR is 70/30, and the contents of CNT in the composites are 1 phr、3 phr、5 phr、7 phr, respectively. The Instron, SEM, DMA, FT-IR, and anti-abrasion tester were used to estimate the performances of the EVA/XNBR/CNT composites. It is showed that the inclusion of CNT could increase the ultimate tensile strength (UTS) of the composites, but the elongation at break decreases. The Young’s modulus of the composites significantly reach a twofold increment as compared to that of the neat EVA/XNBR blends. The inclusion of CNT could also apparently improve the resistance of the composites to the etching to methyl ethyl ketone. The dynamic mechanical analysis showed that the inclusion of CNT could increase both the storage modulus and Young’s modulus of the resulting EVA/XNBR/CNT composites.
