Poly(vinylidene ?uoride) has a crystal part and an amorf part, and is known as semi-crystalin polymers. Poly(vinylidene ?uoride) has piezoelectric property because it has molecule orientation that ful?ll the standard of piezo-electric material. In general there are three phase of those material, that is ?-phase, ?-phase, and ?-phase. Great orientation of molecule that is a piezo-electric stipulation ful?lled by ?-phase. At this experiment, a thin ?lm is made from poly(vinylidene ?uoride) poly- mers, to prove how big an in?uence from a polling (given a high electric ?eld) to yield beta-phase, which causes big piezo-electric property incidence. Poly(vinylidene ?uoride) which is in the form of pellet is thinned to be turned into thin ?lm by milled it using two cylinders that include a heater ?lament. Polling and un-polling samples are analysed by fourier transform infra red(FTIR). Hence, conclusion is obtained: increasing the electric ?eld when applied at pooling time can increase poly(vinylidene ?uoride) molecule orien- tation, marked with many maximum and also minimum top, that is useful for comparison between samples. In PVDF ?lm characterization, infrared with wave number 4000-750 cm?1 is applied. The increasing of molecule orienta- tion can increase the transformation between alpha-phase to beta-phase, and also an improvement of poly(vinylidene ?uoride) ?lm piezo-electric e?ect.
