摘要

A new kind of PTC (positive temperature coefficient) conductive composite and its appliance switching, self-regulating heating cables, for organic polymer alloy filled with carbon black was studied and developed in this paper. The conductive mechanism and the dependence of resistivity on temperature of this system was shed light on, and a new view on PTC effect was set up. Power adjustion coefficient was proposed as a parameter for representign the self-regulating properties was investigated by using several measurement means such as differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD), small angle X-ray scattering (SAXS), dynamic properties, torque analysis and so on, and the experimental results were fully explained.
