摘要

摘要提出了一种利用二氧化硅纳米颗粒(nSiO2)改善典型铁电金属-有机骨架[NH4][Zn(HCOO)3] (AmZn)的相变性能和铁电性的简单方法。结果表明，在nSiO2的影响下，AmZn的一阶过渡类型没有发生改变。随着nSiO2含量从0 wt%增加到40 wt%， AmZn的相变温度显著升高。此外，添加少量nSiO2(< 11%)导致自发饱和度和残余极化率上升。研究还表明，在nSiO2含量高的情况下，很难获得饱和P-E环。

Phase transition and ferroelectricity of composites based on ferroelectric metal-organic framework of [NH4][Zn(HCOO)3]

Abstract The study suggests a simple approach to improve phase transition properties and ferroelectricity of a typical ferroelectric metal-organic framework of [NH4][Zn(HCOO)3] (AmZn) using silicon dioxides nanoparticles (nSiO2). It is shown that the first-order transition type of AmZn is not changed under the influence of nSiO2. Moreover, the phase transition temperature of AmZn significantly increased with increasing the nSiO2 content from 0 to 40 wt%. Besides, the addition of small nSiO2 content (< 11%) led to rising spontaneous saturation and remnant polarizations. The study also indicated difficulties in obtaining the saturation P-E loops at high nSiO2 content.
