Damping property of epoxy-based composite embedded with sol-gel-derived Pb(Zr_(0.53)Ti_(0.47))O_3 thin film

摘要

The Pb(Zr_(0.53)Ti_(0.47))O_3 (PZT) thin films were prepared on Pt/Ti/SiO_2/Si substrate by sol-gel method. The effect of the annealing holding time on microstructure, ferroelectric and dielectric properties was investigated. The single-phase PZT films were obtained with different annealing holding time. PZT films annealed for 30-90 min had better dielectric and ferroelectric properties. The epoxy/ PZT film/epoxy sandwich composites were prepared, and the annealing holding time of PZT films influenced the damping property of the composites. The epoxy-based composites embedded with PZT films annealed for 90 min had largest damping loss factor of 0.906.
