Exploring the Combined Effect of Electron Beam and Conductive Carbon Black on the Mechanical,Dynamic Mechanical,Thermal, and Electrical Properties of Ethylene Acrylic Elastomer

The electron beam-crosslinked and conductive carbon black-reinforced ethylene acrylic elastomer composites have been developed for various applications. The inter-connectivity of conductive carbon black agglomerates are clearly observed from the high-resolution transmission electron photo micrographs. The tensile strength of the composites has remarkably increased with increasing conductive carbon black loading up to 350 radiation dose. The dielectric permittivity (?′) and AC conductivity (σ_ac) increase with an increase in conductive carbon black loading. The electron magnetic shielding interference of the developed composites has been measured using X-band frequency range, and the electron magnetic shielding interference increases with an increase in conductive carbon black loading.
