Electrical Conductivity of Polymer–Carbon Composites: Effects of Different Factors
In this chapter, the electrical conductivity/resistivity of polymer–carbon composites has been discussed in detail. The types of electrical resistivity and their measurement procedure have been depicted pictorially. The electrical conductivity of different carbon materials like diamond, graphite, fullerene, carbon fiber, carbon black, carbon nanotubes, and graphene are noted and discussed. The different techniques of preparation/processing of conducting polymer/carbon composites are mentioned here within short. Moreover, how the geometry/structure of different carbons controls the electrical conductivity of polymer composites has been critically reviewed. The electrical percolation threshold and the conductivity of polymer/carbon composites that depends on many physical and chemical factors are investigated from different literature sources and reported in this chapter.
