Pb(Zr_(0.53)Ti_(0.47))O_3 thin films were fabrcated on Pt/Ti/SiO_2/Si substrates by sol-gel method. The structure and morphology of the thin films were characterized by X-ray diffractometer and atomic force microscopy. The thin films showed a perovskite phase by a change of annealing temperature. And then a composite structure was constructed by the thin films and the epoxy resin. The ferroelectric property of thin films has been improved with rising of annealing temperature. The Pb(Zr_(0.53)Ti_(0.47))O_3 thin films annealed at 750℃ 2Pr value of 68.6μC/cm~2 and 2E_c value of 158.7kV/cm at an applied electric field of 400kV. The density of the thin films has been increased and the damping property of composites has been also improved with the rising of the annealing temperature. When the Pb(Zr_(0.53)Ti_(0.47))O_3 thin films annealed at 800℃, the damping loss factor of the composites has reached the maximum, and the damping temperature range has got the widest.
