(ZH) 改变PVDF-TrFE共聚物末端基团的方法、具有改进铁电性质的PVDF-TrFE共聚物和形成含PVDF-TrFE共聚物的电子装置的方法
Abstract
(EN)
A method of exchanging or transforming end groups in a polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) co-polymer and improving the ferroelectric properties of the PVDF-TrFE co-polymer is disclosed. A bulky or chemically dissimilar end group, such as an iodine or carboxylic acid end group, may be transformed to a hydrogen, fluorine or chlorine atom. A PVDF-TrFE co-polymer comprising end groups or substituents selected from hydrogen, fluorine or chlorine is also disclosed. The co-polymer may be used as a ferroelectric, electromechanical, piezoelectric or dielectric material in an electronic device.

本发明公开了交换或转化聚偏二氟乙烯‑三氟乙烯(PVDF‑TrFE)共聚物中的末端基团并籍此改进PVDF‑TrFE共聚物的铁电性质的方法。大体积或化学上不相似的末端基团,如碘或羟基末端基团,可转化成氢、氟或氯原子。本发明还公开了包含选自氢、氟或氯的末端基团或取代基的PVDF‑TrFE共聚物。所述共聚物在电子装置中可用作铁电、机电、压电或介电材料。
