Electrical And Thermal Properties Of Epoxy Resin Filled With

الملخص EN

Thermal and electrical conductivity of an insulating polymer can be achieved by dispersing conducting particles (e.

g., metal, carbon black) in the polymer.

The resulting materials are referred to as conducting polymer composites.

Electrical and thermal properties of epoxycarbon black composites were studied in this work.

The weight fraction of the carbon blacks ranged from 0.0 up to 20 wt % with the epoxy resin.

By discharging a high voltage through the composite it was found that the resistivity of the composite decreased.

Epoxy-carbon black composites show significant differences from the neat epoxy resin measured in the frequency range.

Conductivity percolation threshold was found when carbon blacks is added in the range of 1 and 2 wt %.

It was found that the epoxy / carbon black composites have better thermal properties than the neat epoxy.
