摘要:

作为铁磁性材料的电等价物,铁电体具有宏观自发电极化,表现出电滞回线等特性,在存储、能量转换、开关、传感等方面得到广泛应用。由于分子材料的特性,分子基铁电体可望作为无机陶瓷铁电体的有益补充和替代。本文围绕铁电的基本概念、原理和特征,针对分子基铁电体的基础研究进展,进行简要综述。

关键词: 铁电, 极化, 相变

Abstract:

As an electrical counterpart to ferromagnets, ferroelectrics are featured by macroscopic spontaneous polarizations which are evidenced by electrical hysteresis loops.Ferroelectrics have been widely used in many fields such as information storage, energy transformation, switching and sensing.Molecule-based ferroelectrics have their advantages over conventional inorganic ferroelectric ceramics and could be used as a complement or an alternative to inorganic ones in many situations.In this paper, we briefly introduced the concept, principle and characteristics of ferroelectrics and summarized the development of molecule-based ferroelectrics.

Key words: Ferroelectricity, Polarization, Phase transition
