中文摘要:
      将PEDOT:PSS(聚3,4-乙撑二氧噻吩/聚苯乙烯磺酸盐)与Bi0.5Sb1.5Te3粉末混合烘干,在液氮下研磨成粉,将粉末经过热压工艺致密化,获得复合热电材料。通过XRD和FESEM表征其相结构和微观形貌,对该样品的电传输性能和热传输性能进行测试,结果表明:在75℃时,质量比90%的Bi0.5Sb1.5Te3复合PEDOT:PSS样品ZT值为0.1,比纯PEDOT:PSS样品高出40倍;复合材料样品Seebeck系数随着Bi0.5Sb1.5Te3的增加大幅提升,无机相连续分布是提高复合材料Seebeck系数的关键。
Remarkably Enhanced Thermoelectric Properties of PEDOT: PSS/ Bi0.5Sb1.5Te3 Composites
英文关键词:PEODT: PSS  Polymer thermoelectric  Seebeck
英文摘要:
      The PEDOT:PSS/Bi0.5Sb1.5Te3 powder was prepared by a solution phase process and grounding in liquid N2. Then the powder was densified by hot press. The polymer composite powder was reformed to polymer bulk. The XRD and FESEM were used to check the phase structure and microstructure. The electrical transport properties and thermal conductivity were measured. The results showed that 90 wt% Bi0.5Sb1.5Te3 with PEDOT: PSS specimen got the highest ZT value of 0.1 at 75 ℃ which is 40 times higher than that of pristine PEDOT: PSS specimen. The Seebeck coefficient was greatly improved with the increase of Bi0.5Sb1.5Te3. The continuous distribution of inorganic phases is the key to improve Seebeck coefficient of composites.
