We present hybrid organic inorganic materials, namely, SrTiO/polyaniline (PANI) composites, with high thermoelectric performance; samples with various SrTiO contents (10, 20, 30, and 50 wt.%) were prepared. The PANI component was obtained through the polymerization of aniline monomers, followed by camphosulfonic acid-doping to enhance its electrical conductivity. SrTiO, with a high Seebeck coefficient, was used as the N-type inorganic componenet; it was synthesized via a one-pot solvothermal methods and, then, dispersed into the conductive PANI matrix. The SrTiO content influenced the Seebeck coefficient and electrical conductivity of the resulting composites. The variations in the thermoelectric properties of the SrTiO/PANI composites consequently changed their power factor; at room temperature, the highest value was ~49.6 μW·m/K, which is 17 times larger than that of pure PANI.
我们展示了具有高热电性能的混合有机无机材料，即 SrTiO/聚苯胺（PANI）复合材料；制备了具有不同 SrTiO 含量（10、20、30 和 50 重量%）的样品。PANI 组分通过苯胺单体的聚合获得，随后进行樟脑磺酸掺杂以提高其电导率。具有高塞贝克系数的 SrTiO 用作 N 型无机组分；它通过一锅溶剂热法合成，然后分散到导电 PANI 基质中。SrTiO 含量影响所得复合材料的塞贝克系数和电导率。SrTiO/PANI 复合材料热电性能的变化因此改变了它们的功率因数；在室温下，最高值约为 49.6 μW·m/K，比纯 PANI 大 17 倍。
