Abstract
Piezoelectric and mechanical properties of uniaxially and two step biaxially drawn poly(vinylidene fluoride) films were investigated and discussed in terms of morphology. Piezoelectric constants(e31) of two step biaxially drawn films were higher than those of uniaxially drawn films under the same poling conditions(about 0.5MV/cm.) In two step biaxially drawn films, dynamic tensile moduli in the drawing direction were higher than those in perpendicular direction to the drawing direction. Thermal stability of two step biaxially drawn films were better than that of uniaxially drawn films.
