Abstract
The effects of γ-irradiation on both the electrical conductivity σ and the penetration rate of benzene in low density polyethylene (LDPE)/styrene butadiene rubber(SBR) conductive blends have been studied. The diffusion coefficient ( D) and the penetration rate ( p) decrease with increasing γ-irradiation dose for unloaded and loaded samples with 1 and 3 phr of LDPE content, presumably due to crosslinking and polymer chain immobilization in the interfacial regions. Meanwhile, both D and p increase for samples loaded with 5 phr of LDPE. The carbon-carbon interspacing distance was found to be highly affected by the γ-irradiation dose, which in turn influences the electrical conductivity of these blends.
