Fabrication of PVDF films has been making using Deep Coating Machine. Preparation of samples carried out for three different solvent concentrations, five of different temperature and three different heating times. This condition is carried out to see the effect of its on piezoelectric properties of PVDF films. The piezoelectric properties like as β fraction are discussion focus in this paper. Piezoelectric properties of PVDF can be improved by solvent concentrations various, temperature and heating time. To obtain the diffraction pattern of sample characterization is performed using X-Ray Diffraction. The β fraction of PVDF films calculate from broadening pattern of X-Ray Diffraction.. Has been obtained an increase piezoelectric properties of PVDF films that characterized by increasing β fraction. Have been obtained β fraction increased 31 %, 39 % and 44.5% for solvent concentrations of 10%, 15% and 20%, respectively. For the heating temperature from 70 0C up to 1100C have been obtained β fraction 37%, 38%, 44%, 50% and 58% respectively. Furthermore for the heating times 10 minute, 20 minute and 30 minute the β fraction are 34%, 48% and 60%. These results indicate that PVDF film results using deep coating method is good. These indication shown as from the β fraction obtained. From the results of sample characterization is known that a good percentage of solvent was 20%, heating temperature 110°C and long heating time is 30 minutes. © 2013 IEEE.
