Most Polymers do not possess natural intrinsic properties that will be enough for them to be used as semi- conductors. In the world trend of industrial growth where polymers seem to be replacing all semi-conductors because of their availability, durability, recyclability and reduced cost, attention is being strongly given to their improvement them for this essential function hence the need for this research.Eight samples each of four polymers; polyethylene (PE), polystyrene (PS), poly propylene (PP),nylon 66 were prepared by doping with different concentrationsof graphite to enhance their electrical and thermal conductivities, considering the fact that they are of different intrinsic properties. The samples were testedfor their electrical and thermal conductivities.It was evident that as the concentration of the graphite dopantincreases, the electrical and thermal conductivities of all the polymers increased although not at the same rate.The most interesting fact is that all polymers that showed highly favorable results in electrical conductivity, showed the least for thermal
