Abstract
The invention reports a new film of the beta phase of polyvinylidene fluoride (PVDF) and its processing for the elimination of porosity, using a compression force along the thickness direction of the sample at a high temperature. The join action of the compression force and the temperature eliminates the porosity of the PVDF beta phase, improving its mechanical (Young's modulus, yielding and breaking stress, yielding and breaking strain), electrical (dielectric constant, electric rupture) and electromechanical properties (electromechanical coupling, piezoelectric coefficients) and, therefore, the use of the material in technological applications. Non-porous material, 95 to 100% in beta phase and with crystallinity degrees higher than 50%, is obtained
