构建复合结构是提高介电储能性能的有效途径。然而，复合材料构件之间的离子扩散通常是不可避免的，这在一定程度上混合了固溶体与复合材料结构对性能的影响。为了尽可能排除离子扩散效应，在较高温度下烧结反铁电(Pb0.97La0.02)(Zr0.5Sn0.4Ti0.1)O3(PLZST)以沉淀SnO2颗粒，然后在(1-x)PLZST:xSnO2(x= 0–0.25)复合材料中引入更多的SnO2。结果表明，复合结构对显微组织和性能有显着影响，其晶格参数发生变化，晶粒尺寸减小，居里温度升高，反铁电性能受到抑制，击穿强度增强。 x= 0.2 的最佳组合显示出 2.38 J/cm3 的高储能密度。这项工作为研究复合材料微观结构对电性能的影响提供了一个强大的平台，有助于进一步开发高性能复合材料。
Constructing composite structure is an effective way to improve dielectric energy storage properties. However, ionic diffusion between composite members is generally inevitable, which mixes the effects of solid solution with composite structure on property to some extent. To exclude the ionic diffusion effect as much as possible, antiferroelectric (Pb0.97La0.02)(Zr0.5Sn0.4Ti0.1)O3(PLZST) was sintered at a relatively high temperature to precipitate SnO2particles, then more SnO2were introduced to from (1-x)PLZST:xSnO2(x= 0–0.25) composite. The results showed that composite structure had significant effects on microstructures and properties with changed lattice parameter, decreased grain size, increased Curie temperature, suppressed antiferroelectric property, and enhanced electric breakdown strength. The optimal composition ofx= 0.2 showed high energy storage density of 2.38 J/cm3. This work provides a robust platform to investigate the effect of composite microstructure on electrical properties, which is helpful for further developing high performance composite materials.
