Newly commercialized PEDOT:PSS products CLEVIOS PH1000 and FE-T, among the most conducting of polymers, show unexpectedly higher Seebeck coefficients than older CLEVIOS P products that were studied by other groups in the past, leading to promising thermoelectric (TE) power factors around 47 μW/m K(2) and 30 μW/m K(2) respectively. By incorporating both n and p type Bi(2)Te(3) ball milled powders into these PEDOT:PSS products, power factor enhancements for both p and n polymer composite materials are achieved. The contact resistance between Bi(2)Te(3) and PEDOT is identified as the limiting factor for further TE property improvement. These composites can be used for all-solution-processed TE devices on flexible substrates as a new fabrication option.
新商业化的 PEDOT:PSS 产品 CLEVIOS PH1000 和 FE-T 是聚合物中导电率最高的产品之一，其 Seebeck 系数比过去其他研究小组研究过的较老的 CLEVIOS P 产品高得令人意外，这导致了有希望的热电（TE）功率因子，分别约为 47 μW/m K(2)和 30 μW/m K(2)。通过将 n 型和 p 型 Bi(2)Te(3)球磨粉末掺入这些 PEDOT:PSS 产品中，实现了 p 型和 n 型聚合物复合材料的功率因子增强。Bi(2)Te(3)和 PEDOT 之间的接触电阻被确定为进一步提高 TE 性能的限制因素。这些复合材料可用作在柔性基底上进行全溶液处理的 TE 器件的新制造选项。
