Study on conducting property of the organic PTCR material

Abstract

The organic PTCR (Positive Temperature Coefficient Resistance) material that consists of the polymer, the conductive particle and additives has been studied in this paper. The crystallinity of the polymer and the dispersivity of the conductive particle can obviously affect conducting property of the material. This property belongs to conductive characteristic of the composite dielectric, and is a kind of crystal-boundary-controlled conduction. The paper has investigated conducting property of the material, in order to gain more applications in energy saving and fire resistance.
