Abstract

Fabrication of PVDF films has been making using Hot Roll Press. Preparation of samples carried out for nine different temperatures. This condition is carried out to see the effect of temperature fabrication on electrical properties and crys- tallite size of PVDF films. The electrical properties like as surface resistivity are discussion focus in this paper. Surface resistivity properties of PVDF can be improved by mechanical treatment on the varying film thickness and the tem- perature. To obtain the diffraction pattern of sample characterization is performed using X-Ray Diffraction. Crystallite size of PVDF films calculate from broadening pattern of X-Ray Diffraction. Furthermore, from the diffraction pattern calculated βfraction and crystallite size, for calculation to determine the crystallite size of the sample by using the Scherrer equation. Has been obtained an increase piezoelectric properties of PVDF films that characterized by increas- ing βfraction. Have been obtained βfraction increased from 25.4% up to 44% for temperatures of 130̊C up to 170̊C, respectively. Resistivity value has been obtained at temperature 130̊C up to 170̊C, decreased from 1.23 × 104Ωm up to 0.21 × 104Ωm respectively. From the experimental results and the calculation of crystallite sizes obtained for the samples with temperature 130̊C up to 170̊C respectively are increased from 7.2 nm up to 20.54 nm. These results in-dicate that mechanical treatment caused increase βfraction and decrease surface resistivity. Increasing temperatures will also increase the size of the crystallite of the sample. This happens because with the increasing temperature causes the higher the degree of crystallization of PVDF film sample is formed, so that the crystallite size also increases
