摘要
The conductive polymer composites and their corresponding resistors with PTC (positive temperature coefficient) characteristic can be manufactured by mixing conductive carbon blacks with poly(vinylidiene fluoride )matrix. The Joule heat can produce when alternative voltage is exerted on the composite resistors, and the resistors can produce when alternative voltage is exerted on the current from flowing at a high temperature because of their PTC effect, thus becoming a kind of important thermoelectric switching materials as heating, temperature-controlling and currentlinfiting element applications.
