| Abstract: | In this paper, the PTC(Positive Temperature Coefficient) effect of carbon black/polyolefine composites has been studied in detail. The conductivity mechanism of this material and some new theoretical feature are introduced, and the main factors of effect on PTC effect and the typical methods of studying this materials are summarized. The technology and properties of base material and conductive filler are discussed in the paper, as well as the effect of outer electric field on the electrical property of the material and PTC effect. This work is important for the research, development and application of PTC composites with high properties. |
