Recently, ionizing radiation has found an application in nanotechnology, especially attributed to the improvement of polymer nanocomposites. In the present paper, we have developed and evaluated nanocomposites of ethylene-octene copolymer (EOC) with 0-15 wt.% of multiwalled carbon nanotubes (MWCNTs) irradiated by 5 MeV accelerated electrons up to constant dose of 150 kGy. The influence of combined factors of MWCNT filler content and the irradiation on the tensile stress-strain properties at 25oC and 50oC and gel fraction was analysed. The results indicated improvement in elastic modulus at both temperatures with an increase of MWCNT content and the irradiation up to 150 kGy dose. The gel content of irradiated EOC/MWCNTs indicated sufficient cross-linking efficacy of EOC with MWCNTs acting as reinforcing fillers in the matrix.
