The techniques were implementedby mixing blend epoxy resins with MWCNTs through magneticstirrer for 15min. Homogenize the blendwas carried out using thehomogenizer equipment ultrasonic liquid processor with high-intensity for 5min and followed by the addition of the hardener to the mixture. The molds prepared by casting EP/MWCNTs composite.The electrical conductivity of EP/MWCNTs compositewas obtained by A.C equipment.The results showed that there was an evolution from insulator state to semiconductor state when increasing the mixing ratios of MWCNTs. The electrical conductivity was improved by three orders than samples of pure epoxy resins matrix.
