Abstract

In our study, Carbon Black / PVC NTC composites were prepared by conventional melt-mixing technique, the resistivity-temperature characteristic of the composites were studied. The results show that the composite possess a lower percolation threshold, a notable negative temperature coefficient (NTC). the volume resistivity was reduced, when carbon black filling rate increased to a characteristic value, the resistivity reached 5 to 10 orders of magnitude, from the SEM photograph of composite, the dark and light areas were relatively distributed, the dispersion effect of the carbon black was good.
