摘　　要：反铁电材料在发生场致反铁电-铁电相变过程中伴随着巨大应变和能量的储存和释放,故在高密度储能器件和机电换能器上极具应用潜力。综述了具有钙钛矿结构的Pb基反铁电体结构特点与性能调控,特别是Pb(Zr,Ti)O3(PZT)基反铁电储能材料的研究进展与存在问题。重点讨论了几类典型元素掺杂Pb基反铁电薄膜材料研究的最新进展。简要介绍了适应无铅化要求、环境友好的无铅钙钛矿型反铁电-铁电相变材料。最后对当前钙钛矿型Pb基反铁电材料研究与应用中尚需深入探究的问题进行了总结。The antiferroelectric materials are accompanied by huge strain and energy storage and release in the process of field-induced antiferroelectric-ferroelectric phase transition, which make them great potential in high-density energy storage devices and electromechanical transducers. An overview is given on the structure features and properties improvement of perovskite Pb-base antiferroelectric materials. The research progress as well as the problems on Pb （ Zr, Ti） O3 （PZT） - based antiferroelectric material are reviewed. Particularly, several types of doped PZT-based antiferroelectric thin films that receive extensive attention are mainly discussed. To meet the environmental requirements, lead-free perovskite antiferroelectric-ferroelectric phase change materials are introduced. Finally, some issues that worth further exploration are summarized and corresponding prospects are proposed on the research and application developments of the antiferroelectric perovskite Pb-based materials.
