The growing demand for clean energy catalyzes the development of new devices capable of generating electricity from renewable energy resources. One of the possible approaches focuses on the use of thermoelectric materials (TE), which may utilize waste heat, water, and solar thermal energy to generate electrical power. An improvement of the performance of such devices may be achieved through the development of composites made of an organic matrix filled with nanostructured thermoelectric materials working in a synergetic way. The first step towards such designs requires a better understanding of the fundamental interactions between available materials. In this paper, this matter is investigated and the questions regarding the change of electrical and thermal properties of nanocomposites based on low-conductive polypyrrole enriched with bismuth nanowires of well-defined geometry and morphology is answered. It is clearly demonstrated that the electrical conductivity and the Seebeck coefficient may be tuned either simultaneously or separately within particular Bi NWs content ranges, and that both parameters may be increased at the same time.
对清洁能源日益增长的需求推动了能够从可再生能源资源发电的新设备的发展。一种可能的方法集中在使用热电材料（TE），其可以利用废热、水和太阳能热能来发电。通过开发由填充有以协同方式工作的纳米结构热电材料的有机基质制成的复合材料，可以实现此类设备性能的提升。迈向此类设计的第一步需要更好地理解可用材料之间的基本相互作用。在本文中，对此问题进行了研究，并回答了有关基于富含具有明确几何形状和形态的铋纳米线的低导电聚吡咯的纳米复合材料的电学和热学性质变化的问题。清楚地表明，在特定的铋纳米线含量范围内，可以同时或分别调节电导率和塞贝克系数，并且这两个参数可以同时增加。
