摘要

碳原子数n=6 ~ 11,13的间二甲二烷和脂肪族二羧酸聚酰胺(简称MXD n)，无论n为奇数还是偶数，均表现出D-E(电位移-电场)迟滞。剩余极化范围为23 ~ 67 mCm/sup -2/，在玻璃化转变附近的高温下迅速消失。尼龙mxdn的铁电行为可能与酰胺基在高电场下在非晶区排列有关。

Ferroelectric behavior in nylons of metaxylylenediamine and aliphatic dicarboxylic acids

Polyamides of m-xylylenediane and aliphatic dicarboxylic acids with the number of carbon atoms n=6-11,13 (abbreviated to MXD n) exhibited D-E (electric displacement-electric field) hysteresis for quenched samples irrespective as to whether n was odd or even. The remanent polarization ranged from 23 to 67 mCm/sup -2/, vanishing rapidly at high temperature near the glass transition. The ferroelectric behavior in nylon MXD n is likely related to the alignment of amide groups at high electric field in amorphous regions.<>
