Anotācija Radiation crosslinking could improve strength, thermal and electrical properties of antistatic coating and electromagnetic shielding elastomeric nanocomposites. In this work, ethylene-octene copolymer elastomer with multi-walled carbon nanotubes (CNT content 0-15 wt.%) was irradiated up to 150 and 300 kGy absorbed doses. The gel content of EOC/CNTs increased by 5% at 1 wt.% filler content and remained at 60-80% due to predominant cross-linking of EOC at filler content 0-15 wt.%. The DSC studies indicated slight reduction of crystallization temperature due to reduced order of EOC spot type lamellar structure with increase of both irradiation dose and CNT content in the composites. The nucleation effect of CNT within the reorganization in cross-linked structure induced growth in crystallinity. The modulus of elasticity increased by 2-fold with increase of the filler content. Impedance and resistivity contributed to prevented charge movements in case of cross-linked macromolecular structure; the polarization effect of CNT interactions influenced the growth of dielectric constant by up to 6 times with the filler content reaching 15 wt.%.
