R. Sivakumar, S. Nirmala

The present work was made to study the electrical conductivity of polyethylene terephthalate (PET) thin films. The thickness of the sample thin films of the order of 100-250 microns. The electrical conductivity values of PET thin films dependence on its physical and chemical properties. The main aim of this work is finding the Resistivity values of the PET thin films; from this we can calculate the electrical conductivity of the polymer material (inverse of Resistivity is conductivity). In this study the electrical conducting properties of polymer polyethylene terephthalate has been investigated by using a four-probe apparatus because of its importance in industrial applications. The dependence of DC (direct current) surface resistance on thickness was measured using this method. The surface resistance exhibits the size effect in accordance with the sample (PET) material. The readings are taken with different combination materials such as copper, aluminum carbon strips etc. According to this study suggests that possibility of using PET thin films in electronic components (capacitors, resistors, etc) that operate at temperature dependence applications and this classification not only for polyethylene terephthalate (PET) thin films but also for the other polymer materials
