在室温下通过界面法合成硒化银-聚苯胺纳米复合颗粒。粉末X-射线衍射分析与红外分析证实了样品的相组成,透射电子显微镜观察表明复合颗粒为核壳结构:衬度较浅的聚苯胺为壳而衬度较深的硒化银为核。对硒化银-聚苯胺纳米核壳结构的形成机理做了探讨。所得粉末经冷压成型后测试其热电性能,常温下样品的电导率和Seebeck系数分别为5.5S·m-1和179μV·K-1。
Synthesis of silver selenide - polyaniline nanocomposite particles by interfacial method at room temperature. Powder X-ray diffraction analysis and infrared analysis confirmed the phase composition of the sample, transmission electron microscopy showed that the composite particles are core-shell structure: polyaniline lighter shell and darker silver selenide as the core. The formation mechanism of silver selenide-polyaniline nano-shell structure was discussed. The resulting powders were tested for their thermoelectric properties after cold forming. The conductivity and Seebeck coefficients of the samples were 5.5 S · m-1 and 179 μV · K-1, respectively.
