Jayanth Kumar S, Anjana Jain

Abstract :

<p>Piezoelectric materials have been major area of focus for development of sensors and actuators for almost a century. Apart from the single–phase materials like polymers, copolymers have also been studied extensively in terms of achieving combination of material properties, tailoring of parameters and ease of faication. One such copolymer is Poly(vinylidene fluoride)/trifluoroethylene [P(VDF–TrFE)], which exhibits attractive properties to make it useful as transducers in various applications. Being dielectric material, the investigation of dielectric properties of P(VDF–TrFE) is essential. In the present investigation, copolymer films were prepared by hot press method and their dielectric properties have been investigated. Since P(VDF–TrFE) film has good thermal stability, the effect of temperature on dielectric properties of P(VDF–TrFE) copolymer has also been studied. Present work evaluates the dielectric properties such as relative permittivity, capacitance, dielectric loss and intrinsic conductivity, etc. of these films as function of frequency at various temperatures</p>
