Poly(vinyl fluoride) films were elongated twice the original length by rolling, subjected to a d.c. field of 350 kV/cm at 80℃ for 90 minutes, and cooled down to room temperature for 2 hours. The piezoelectric strain-constant d of the electret films was about 1×10^<-8> cgs esu at room temperature. The complex piezoelectric, elastic, and dielectric constants showed two dispersions at the low and high temperatures, respectively. The maximum value of piezoelectric loss factor tanδ_d is roughly the same as the sum of the maximum values of elastic and dielectric loss factor tanδ_Ξ and tanδ_ε. This fact may be explained by assuming that the piezoelectric constant h is a real quantity.
