摘要:

合成了窄带隙的聚(3-甲基噻吩对硝基苯甲烯)(PMTNBQ), 并研究了其热电性能. 通过溶液混合、 机械球磨以及冷压成型, 制备了具有不同复合比例的PMTNBQ/石墨(G)的复合热电材料. 研究了石墨含量对PMTNBQ/G复合材料的热电性能的影响. 当石墨含量(质量分数)为90%时, PMTNBQ/G复合热电材料出现了最高的热电优值(ZT)(5.36×10-3).

关键词: 聚(3-甲基噻吩对硝基苯甲烯), 石墨, 复合材料, 热电材料

Abstract:

Poly{(3-methylthiophene-2,5-diyl)[p-(nitro)benzylidene](3-methylthiophenylene quinodime-thane-2,5-diyl)}(PMTNBQ) with low bandgap was synthesized and its thermoelectric properties were investigated. PMTNBQ/graphite(G) composites were prepared by mixing in solution followed by mechanical ball milling and cold pressing. The thermoelectric properties of the composites were investigated as a function of the graphite to polymer ratios. The highest value of ZT(5.36×10-3) was obtained for the PMTNBQ/G composite containing 90%(mass fraction) of G. This work suggests that the thermoelectric properties of polymer-inorganic composites can be improved by synthesizing polymers with low band gap.

Key words: Poly{(3-methylthiophene-2, 5-diyl)[p-(nitro)benzylidene](3-methylthiophenylenequinodimethane-2, 5-diyl)}, Graphite, Composite, Thermoelectric material
