Introduction. Many electronic components and devicesare being made from polymer-based composites. For polymer-based composites being used in these applications, a highelectrical conductivity is required to provide electrostaticdischarge (ESD) and electro magnetic interference (EMI)shielding. As electronic devices become smaller and faster, theirsensitivity to static discharge increases and the need for anincreased rate of ESD becomes vital. Conventionally, conductivefillers such as carbon black are incorporated into polymers inorder to achieve electrical conductivity above the required orderof 10
