对氮冠醚(NC)和花生酸(AA)LB膜(Z型以及交替Y型)的铁电性进行了研究.结果发现:在氮冠醚/花生酸交替Y型LB膜、掺Ba~(2+)的和掺Mn~(2+)的花生酸的Z型膜以及纯的氮冠醚和花生酸的Z型膜中均观察到了电滞回线,亦即说明它们都具有铁电性,并且它们各自对应的剩余极化强度大小分别为:9400,180,650,450和15μC·m~2.由此可以推知:Ba~(2+) ,Mn~(2+)等离子掺入的离子转移效应以及交替膜的层间相互作用对LB膜的铁电性有比较大的增强效应.
The ferroelectric properties of nitrogen-crown ether (NC) and arachidonic acid (LB) films (Z-type and alternate Y-type) were studied. Hysteresis loops were observed both in the Z-membrane of (2+) and Mn 2+ -charged arachidic acid and in Z-membrane of pure azon crown ether and arachidic acid, indicating that they both have ferroelectric , And their corresponding remanent polarization intensities are respectively 9400, 180, 650, 450 and 15μC · m ~ 2. It can be deduced that the ion transfer effect of Ba 2+ and Mn 2+ ions As well as the interlayer interaction of alternating films on the ferroelectricity of LB films have a greater enhancement effect.
