Abstract

The invention discloses a conjugated organic metal polymer containing nitroxide free radicals and ferrocene groups, a preparation method and application of the conjugated organic metal polymer and a composite thermoelectric thin film. The invention provides three metal organic conjugated polymers. The three metal organic conjugated polymers comprise a polymer formed by connecting 9-(ferrocenyl methylene)-9H-fluorene with triphenylamine containing TEMPO in a single bond form; the invention relates to a polymer formed by connecting 9-(ferrocenyl methylene)-9H-fluorene with triphenylamine containing TEMPO in a triple bond form. A ferrocene group is directly connected with triphenylamine containing TEMPO in a single bond form. The metal organic conjugated polymer and single-walled carbon nanotubes (SWCNTs) form a composite material, the application of the composite material in the thermoelectric field is researched, and the highest power factor (PF) of the composite thermoelectric film is 156.5 +/-1.6 mu W m <-1 > K <-2 >. 本发明公开含有氮氧自由基与二茂铁基团的共轭有机金属聚合物及制备方法与应用、复合热电薄膜。本发明提供了三种金属有机共轭聚合物，包括：9‑(二茂铁基亚甲基)‑9H‑芴以单键形式与含TEMPO的三苯胺相连的聚合物；9‑(二茂铁基亚甲基)‑9H‑芴以三键形式与含TEMPO的三苯胺相连的聚合物；二茂铁基团直接以单键形式与含TEMPO的三苯胺相连的聚合物。本发明所述金属有机共轭聚合物与单壁碳纳米管(SWCNTs)形成复合材料，研究其在热电领域的应用，本发明复合热电薄膜中的最高功率因数(PF)为156.5±1.6μW m‑1K‑2。
