摘要:
An increase in surface voltage decay time has been noted in corona‐charged polyvinylidene fluoride films solution cast on silicon, once these films have been charged a number of times and annealed. A re‐examination of the fundamental equations that describe these surface voltage decays shows that the relaxation of the electric field inside the polymer may be considerably lengthened, when the trapped charge density is comparable to the thermal free‐ carrier density.
