It is considered that electrical conduction in polymer in releatively low electric field is ionic. Here investigates about resistivity of ionic conduction and dielectric loss tangent for various polymer films.<br>Temperature dependence of resistivity is expressed by the following Arrhenius equation, ρ=ρo exp (E/RT), where ρ is the resistivity, ρo is a constant, E is the activation energy, R is a gas constant and T is the absolute temperature.<br>Usually, transport phenomena such as mobility, viscosity, diffusion and so on show a compensation effect. Ionic conduction in polymer is also shown a compensation effect equation as ρo=a exp (bE), where a and b are constants.<br>Polymer has properties of glass and rubber state below and above glass transition temperature. Although these states have each compensation effect, we find the compensation effect of three types. One is that of amorphous polymer such as PEI (Polyetherimide), the second is that of crystallized polymer such as PET (Polyethylene terephthalate), and the third is that of crystallized polymer above glass transition temperature.<br>In this study, an equation, which can calculate the activation energy of resistivity, is deduced by using compensation effect.
