電子線으로 照射된 低密度 Polyethylene의 電氣傳導度와 溫度特性

Electric Conductivity and Temperature Characteristics of Irradiated Low density Polyethylene

Conductivity in polyethylene has been investigated as the applied electric fields between 1.1×10⁴ and 2.5×10⁵ V/cm and temperature from 20°C to 105°C. The comparative analysis of the theory with the experiment results were tried on the assumption that the current is composed of eletrons injected into sample which contains space charge over the Schottky barrier. From the results a rough estimate was made of the density of traps in irradiated polyethylene and the activation energy, which could be calculated from the temperature dependence of electrical conductivities of polyethylene irradiated with 10⁸rad electron beam, were obtained 0.28 eV and 1.06eV,
