제목 Temperature Dependency of Resistivity for the Carbon Black Filled-PMC
초록  The percolation property of carbon black-filled PMC (polyethylene matrix composites) below the percolation threshold has been discussed with the hopping conduction model. This study investigates the electrical conduction property of the composites below the percolation threshold based on the frequency dependence of conductivity in the range of 20 Hz to 1 MHz. There are two components for observed ac loss current. One is independent of frequency and becomes prevalent in low frequencies just below the percolation threshold and under high electrical field. The other is proportional to the frequency of applied ac voltage in high frequencies and its origin is not clear. pping conduction model. These results support the conclusion that the electrical conduction mechanism below the percolation threshold is tunneling.
