A significant influence of the molecular weight on dielectric properties and piezoelectric constant poly(vinylidene fluoride) (PVDF) membranes obtained by electrospinning was demonstrated. Electrochemical impedance spectroscopy d33 meter were used to evaluate respectively. The presence β-phase determined Fourier transform infrared (FTIR) X-Ray diffraction (XRD). with lowest (180,000 g/mol) poss...
