A ternary hybrid nanocomposite of RGO–CdS–polyaniline (PANI) is prepared by a simple two stage in situ method for its thermoelectric studies. For this purpose, CdS quantum dots were first prepared with varying concentrations in the presence of reduced graphene oxide to form RGO–CdS nanocomposites using 3-mercaptopropionic acid as a linker. Polyaniline was then prepared in situ in the presence of RGO–CdS nanocomposites to eventually obtain RGO–CdS–PANI nanocomposites. The electrical conductivity, Seebeck coefficient and power factor of the RGO–CdS–PANI nanocomposites were calculated with various loadings of RGO–CdS nanocomposites in PANI. The final RGO–CdS–PANI nanocomposites delivered a high electric conductivity in the order of 10⁵ S m⁻¹ and showed strong re-dispersion in DMF and ethanol. The effective band alignment and decreased thermal conductivity in RGO–CdS–PANI nanocomposites resulted in p-type behaviour and a high power factor value.

乐队设计的用于热电应用的p型RGO–CdS–PANI三元纳米复合材料

RGO-CdS-聚苯胺（PANI）的三元杂化纳米复合材料是通过简单的两步原位热电学方法制备的。为此，首先使用3-巯基丙酸作为连接剂，在还原的氧化石墨烯存在下，以不同的浓度制备CdS量子点，以形成RGO-CdS纳米复合材料。然后在RGO-CdS纳米复合材料存在下原位制备聚苯胺，最终获得RGO-CdS-PANI纳米复合材料。RGO–CdS–PANI纳米复合材料的电导率，塞贝克系数和功率因数是根据PANI中各种RGO–CdS纳米复合材料的负载量计算得出的。最终的RGO–CdS–PANI纳米复合材料具有10 ⁵ S m ^-1数量级的高电导率并显示出在DMF和乙醇中的强烈再分散。RGO-CdS-PANI纳米复合材料的有效能带排列和降低的热导率导致p型行为和高功率因数。
