Conductive Thermoset Composites

Halima Khatoon, Sajid Iqbal, Sharif Ahmad

Conductive thermoset composites (CTC) have gained much attention among scientists and technologists due to their excellent electrical, mechanical, and thermal properties. These properties of CTC make them a superior candidate in various applications like EMI shielding, anti-corrosive coatings, electronic packaging, LED’s, etc. In view of this, the present chapter highlights the significance of CTC along with the historical background of some important thermoset polymers, different types of CTC and their methods of synthesis. In addition to this, the applications of CTC are described. Moreover, the problems associated with CTC and their solutions are discussed in detail.
