Abstract

This paper reports on a high voltage measurement set-up for determiningthe relative permittivity and the volume resistivity of dielectric polymers.These properties were evaluated on thin films at electric fields up to 80 V µm−1 and in the quasi-static regime at frequencies lower than 1 Hz. It is found that the high fieldproperties of FEP, PFA, polyimide and Mylar are comparable to the respective low fieldvalues, while for ferroelectric PVDF poling behavior becomes evident at high fields. Highfield properties of dielectric polymers are of particular importance in the design of devicesrelying on electrostatic attraction, such as electro-bonded laminates applied in tunablebending stiffness structures.
