Study on NTC Electrical Behavior of Carbon Black/PVC Composite
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.
