The enhancement of high dielectric properties for pure PVDF-HFP by using the suitable stirred temperature and time

Abstract

Abstract A novel light-weight electronic device from the dielectric polymer is so remarkable as the actuators, sensors, energy storage device and energy conversion. For this work, the thin film electroactive polymer is fabricated by casting technique which PVDF-HFP dissolve in N,N-dimethylformamide (DMF). The three stirred temperatures (30, 55 and 80 °C) and two stirred times (6 and 12 h) are completely considering. The highest polarization as the β phase is also considered for dielectric properties improvement. The FTIR, LCR and DSC equipment are used to measure the electroactive improvement. As a result, the 12 h stirred time with 30 °C stirred temperature is the best condition. The 0.25 g/ml concentration is also the suitable condition. The better dielectric properties are the requisite condition for a novel energy storage device in the future.
