ABSTRACT:
An improved method of inducing piezoelectric properties in polymer films, ch as polyvinylidene fluoride (PVDF) films and co-polymers thereof. This improved method involves applying uniaxial tensile forces to pre-aligned polymer films while simultaneously applying an electric poling field to the pre-aligned polymer films at room temperature to provide enhanced piezoelectric properties. This improved method does not require the use of heating equipment or temperature cycling equipment during the electric field poling of the polymer and thus represents a simpler and more cost efficient process of inducing piezoelectric properties in polymers.
