Characteistics of Charge Traps and Poling Behavior of Poly (Vinylidene Fluoride)
서정원,류균상,이호성,Seo Jeong Won,Ryoo Kun Sang,Lee Hoo Sung Korean Chemical Society 1985 Bulletin of the Korean Chemical Society Vol.6 No.4
Transient charging and discharging currents as well as space charge limited currents have been measured in biaxially stretched poly(vinylidene fluoride) film under various poling fields and temperatures. At low temperatures and short poling times, the I-V characteristics showed shallow trap behavior. When the current values extrapolated to the infinite time, the I-V characteristics indicate that the distribution of the trap energy levels is uniform or very broad. The abnormal suppression of current at higher poling voltages and the high discharge rate observed also in the same voltage range are attributed to the morphological changes due to dipole reorientation.
