Thermal and Electrical Properties of Irradiated Styrene Butadiene Rubber-Metal Composites

Abstract

The effect of γ- radiation on both the electrical and thermal properties
of styrene butadiene rubber (SBR) loaded with different concentration ratios of
copper (Cu) and iron (Fe) fine powder has been studied. The d.c. electrical
conductivity σ for all loaded SBR composites was highly affected by γ -
radiation dose. The addition of different fillers do not contribute much to the
thermal properties of these composites. The filler – filler inter-spacing distance
was found to be highly affected by the γ- radiation dose, which in turn
influences the electrical conductivity of these composites.
