项目摘要
In order to improve the thermal stability of the electronic conductivity of polypyrrole(PPy), a series of aromatic sulfonate derivatives having acid-type substitute groups, such as -COGH, -OH, and SO_3H, were used as a dopants. The PPy doped with these dopants showed excellent thermal stability of their electric conductivity, even at 150゚C in air. Especially, 2-hydroxy-5-sulfobezoic acid provided the highest thermal stability. The doped PPy maintained 95 % of its initial conductivity even after heating for 8 h at 150*in air and showed 20-times higher stability against long-term heating at 125*for 1000 h in comparison with PPy doped p-methylbenzoic acid.The thermal stabilization mechanism has suggested hat dopants having acidic substituents should suppress proton dissociation from the N-position of the PPy and keep the p-conjugation structure by supplying a proton from acidic groups. Such a proton supplement was confirmed by the IR spectroscopy of deuterized PPy.Their PPys were applicable to use an electrode material of battery and capacitor. The capacitor using PPy doped the antioxidative dopant provides high reliability under high temperature in air for long-term with good high frequency properties.
为了提高聚吡咯(PPy)的电子电导率的热稳定性,采用一系列具有酸型取代基的芳香族磺酸盐衍生物,如-COGH、-OH、SO_3H等作为掺杂剂。掺杂这些掺杂剂的 PPy 即使在 150°C 的空气中也表现出优异的电导率热稳定性。特别是,2-羟基-5-磺基苯甲酸提供了最高的热稳定性。即使在空气中150*加热8小时后,掺杂的PPy仍能保持其初始电导率的95%,并且与掺杂PPy的对甲基苯甲酸相比,在125*1000小时的长期加热下表现出高20倍的稳定性。热稳定机制表明,具有酸性取代基的掺杂剂应抑制质子从PPy的N位解离并保持p-共轭。 通过从酸性基团提供质子来结构。这种质子补充通过氘化PPy的红外光谱证实。他们的PPy适用于电池和电容器的电极材料。使用PPy掺杂抗氧化掺杂剂的电容器在空气中高温下长期具有高可靠性,并具有良好的高频特性。
