The paper reports the development of compression moulded pre-localized graphite/polyvinyl chloride (graphite/PVC) segregated composites with different concentrations of graphite and their application to the shield effectiveness of electromagnetic radiation in the X-band frequency range 8-12 GHz. The incorporation of graphite is related to the formation of conducting channels. It is found that conducting channels are formed above 3 wt. % of graphite. The electrical conductivity is also found to be strongly dependent on the graphite content, and the data are analysed using a percolation model. Variations in SE with graphite loading, due to changes in the conductivity of the composite, have been investigated.
