Conductive polymer) composites (CPCs) (c) conductive fillers and polymer (matrix).have attracted many researchers due to (ther) popular applications, such as electromagnetic interference shielding, antistatic materials, and sensors, etc.For CPCs, a low percolation threshold (i.e., the conductive filler content at insulator/conductor transition) leads to a good processability, good mechanical properties and a low cost.
