Abstract:
     The invention discloses the polymer conducting composite material, belonging to electric component field. The method comprises 70-95% elastomeric polymer, 0.1-20% magnetic behaviour conductivity filler, 0-4% inactive filler and 0.1-6% auxiliary agent. The conductivity filler is orientation arrangement in polymer, realizing by magnetic field. The arrangement of conductivity filler and electrical network are decided by filler content, magnetic field intensity, polymer viscosity, thermal insulation time and sulfuration time. The electrical resistivity of the material displays the switching effect of positive temperature coefficient, positive stretching force coefficient, negative pressure coefficient and positive shear coefficient, so the material can be used to make PTC resistor, stressing sensing element, torque sensor and overload protection device.
