Preparation and dielectric properties of PZT /PVDF composite materials

PZT materials possess high dielectric constant, while PVDF has good flexibility. Flexible PZT/ PVDF composite materials with certain thickness can be prepared through chemical dissolution, spin coating to form a single layer film and hot compression of multi-layer films into one. The dielectric constant and dielectric loss of the film were measured, compared and analyzed. And it can be derived to be a material with high dielectric constant, low loss and high flexibility. Miniature of microstrip antenna design can be achieved on such a material.
