Molten Salt Conversion of Plastics into Highly Conductive Carbon Nanostructures

  • Ali Reza KamaliEmail author
Chapter

Abstract

The pollution caused by the increasing accumulation of plastic wastes in the environment is considered a serious emerging threat to our wildlife, habitats and to us. In fact, the efficient removal of plastic wastes from the environment is challenging in the absence of a strong economic driving force. Such a driving force can be achieved through the low-cost conversion of plastic wastes into highly valuable outputs such as high-quality graphene materials. This chapter provides an introduction into thermokinetic characterization of polyethylene terephthalate, the most commonly used plastic, and then deals with the molten salt—assisted conversion of plastic bottles into graphene nanostructures with a high surface area, degree of crystallinity and electrical conductivity.
