| Abstract: | This study presents an innovative approach to the production of reinforced elastomer composites filled with carbon black Printex XE-2B, using the calendering process and ionic liquids (ILs) as dispersing agents. The effect of Printex XE-2B on the mechanical and electrical properties of acrylonitrile-butadiene rubber (NBR) composites was compared to that of conventional carbon black Humex N339. It was found that the highly structured Printex XE-2B significantly enhanced both the mechanical and electrical properties of the NBR composites, in contrast to standard Humex N339. To obtain uniform filler dispersion in the polymer matrix, several different ILs were employed as dispersing agents. The application of ILs had a considerable effect on the properties of the prepared composites, due to the improved dispersion of the filler particles in the composite matrix, which favored the formation of ‘conductive paths.’ Importantly, the prepared NBR/Printex XE-2B/IL composites were found to have reversible and repeatable electrical properties following exposure to chloroform vapors. |
