제목 Temperature dependency of dielectric property for the carbon black-filled PMC
초록   Temperature dependence of dielectric property of the carbon black-filled polyethylene matrix composites below the percolation threshold is studied based on the effect medium approximation theory(EMA theory). Although literature on the calculation based on the EMA theory by changing the parameters is vast, an overall discussion taking into account the EMA theory is required in order to explain the dielectric properties of the composites, the temperature dependence of them, for example. Changes of dielectric properties and the temperature dependence of them of the composites made of carbon particle and polyethylene below the percolation threshold for the volume fraction of carbon black have been discussed based on the EMA theory. The composites is satisfied with the universal law of conductivity above percolation threshold whereas it gives the critical exponent of s=1 for dielectric constant below percolation threshold.
