Abstract

The invention discloses a non-conjugated organic polymer containing nitroxide free radicals and ferrocene groups, a preparation method and application of the non-conjugated organic polymer, and a composite thermoelectric thin film. The structural general formula of the non-conjugated organic polymer is shown in the specification, and in the formula, R is selected from any one of 4-nitrogen oxide-(tert-butyl)-2, 3, 5, 6-tetrafluorobenzene, 2-methyl-nitrogen oxide-N-(perfluorophenyl) pentanamide and 2, 2, 6, 6-tetramethylpiperidine-nitro-oxide-4-yl acetate. A non-conjugated organic polymer containing a nitroxide free radical (N-O) and a ferrocene group is designed and synthesized, the non-conjugated organic polymer is compounded with a single-walled carbon nanotube to form the composite thermoelectric film, and the composite thermoelectric film has high Seebeck coefficient and conductivity, so that the composite thermoelectric film has excellent thermoelectric performance. 本发明公开含有氮氧自由基与二茂铁基团的非共轭有机聚合物及其制备方法与应用、复合热电薄膜。该非共轭有机聚合物的结构通式如下式所示：其中，R选自4‑氮氧化物‑(叔丁基)‑2,3,5,6‑四氟苯、2‑甲基‑氮氧化物‑N‑(全氟苯基)戊酰胺、2,2,6,6‑四甲基哌啶‑氮‑氧化物‑4‑基乙酸酯中的任意一种。本发明设计并合成了一类含有氮氧自由基(N‑O)与二茂铁基团的非共轭有机聚合物，将其与单壁碳纳米管复合形成复合热电薄膜，本发明中的复合热电薄膜具有较高的Seebeck系数和导电率，使得复合热电薄膜具有优异的热电性能。
