Abstract
In this chapter, the focus has been put on the electrical conductivity of polymer/graphene composites prepared by different techniques. Initially, we discussed the electrical conductivity of different types of graphenes like pristine graphene, graphene oxide (GO), reduced GO, chemically vapor deposited graphene, and liquid exfoliated graphene. Thermally exfoliated pristine graphene showed the highest electrical conductivity; whereas, highly functionalized GO exhibited the lowest conductivity. The electrical percolation threshold and the ultimate conductivity values of these graphene-based polymer composites are reported and discussed elaborately. Several dependent phenomena of electrical conductivity like types of polymer and graphene, loading of graphene, processing techniques, alignment of graphene etc. are presented here in details. Finally, possible applications of these conductive polymer/graphene composites like sensors, electromagnetic interference shielding are mentioned within the text.
