Abstract
En 中文
In polymer ferroelectrics, spontaneous polarization is linked to the symmetry breaking of permanent dipolar elements, which usually arises from strong dipolar interactions or introduced chirality. Recently, there have been rapid and significant advances in understanding how molecular design and dipolar interactions dictate ferroelectric order in the soft matter field. These insights could greatly enhance our comprehension of polymer ferroelectrics and prompt a reevaluation of their design principles. In this review, we explore the origins of ferroelectricity in polymers, highlighting the critical role of dipolar interactions. We present a comprehensive collection and categorization of all polymer ferroelectrics, including both fluorinated and non-fluorinated systems. Additionally, we discuss domain size, domain wall, and topological engineering of polymer ferroelectrics, followed by an examination of representative and emerging applications. Finally, we offer perspectives on the future development of polymer ferroelectrics, focusing on novel non-fluorinated polymer systems, the flexible tuning of physical properties and performance, and the precise control of topology and polarization distribution.
