remains rare. In this paper, two series of poly(Schiff base)s with either C=C or C≡C linker and their metallopolymers were synthesized and doped with single-walled carbon nanotubes to evaluate how the linking groups affected the TE properties of the resulting composites. Apart from the effect exerted by the morphology, experimental results suggested that the linkers played a key role in determining the band
由于聚合物基热电(TE)材料具有重量轻、柔韧、低毒和易于加工等吸引人的特性,近年来开发出越来越多的具有高热电性能的导电聚合物及其复合材料。然而,迄今为止,关注结构-性能关系的研究仍然很少见。在本文中,合成了两个系列的具有 C=C 或 C≡C 连接体的聚(席夫碱)及其金属聚合物,并用单壁碳纳米管掺杂,以评估连接基团如何影响所得复合材料的热电性能. 除了形态产生的影响外,实验结果表明接头在决定带隙、优选的分子构象和聚合物的共轭程度方面起着关键作用,这成为影响所得材料热电性能的关键因素。此外,通过与过渡金属离子配位,可以很容易地调整 TE 特性。
