摘要 介绍了一种新型氟化有机硅氧烷材料的物理特性，并与其非氟化同系物进行了比较。氟化材料在 100°C 的宽温度范围内具有高 Ps (200–450 nC/cm2) 和高倾斜角 (∼38°)。两种材料均表现出反铁电相。当氟化材料冷却时，其行为变得更像铁电体。我们讨论与材料分子结构相关的这种行为。
Abstract The physical characteristics of a new fluorinated organosiloxane material are presented, and compared to those of its non-fluorinated homologue. The fluorinated material has a high Ps (200–450 nC/cm2) and a high tilt angle (∼38°) over a 100°C wide temperature range. Both materials exhibit antiferroelectric phases. As the fluorinated material is cooled, its behaviour becomes more ferroelectric-like. We discuss this behaviour in relation to the molecular structure of the materials.
