The thermal, mechanical and electrical properties of polymeric composites combined using polythiophene (PT) dopped by FeCl and polyamide 6 (PA), in the aspect of conductive constructive elements for organic solar cells, depend on the molecular structure and morphology of materials as well as the method of preparing the species. This study was focused on disclosing the impact of the polythiophene content on properties of electrospun fibers. The elements for investigation were prepared using electrospinning applying two substrates. The study revealed the impact of the substrate on the conductive properties of composites. In this study composites exhibited good thermal stability, with T values in the range of 230-268 °C that increased with increasing PT content. The prepared composites exhibited comparable PA T values, which indicates their suitability for processing. Instrumental analysis of polymers and composites was carried out using Fourier Transform Infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA) and scanning electron microscopy (SEM).
就有机太阳能电池的导电结构元件而言，使用经FeCl掺杂的聚噻吩（PT）与聚酰胺6（PA）复合而成的聚合物复合材料的热、机械和电性能，取决于材料的分子结构和形态以及制备该材料的方法。本研究的重点是揭示聚噻吩含量对电纺纤维性能的影响。研究用的材料是通过静电纺丝法使用两种基底制备的。该研究揭示了基底对复合材料导电性能的影响。在本研究中，复合材料表现出良好的热稳定性，其T值在230 - 268℃范围内，且随着PT含量的增加而升高。所制备的复合材料表现出与PA相当的T值，这表明它们适合加工。使用傅里叶变换红外光谱（FT - IR）、热重分析（TGA）、差示扫描量热法（DSC）、动态热机械分析（DMTA）和扫描电子显微镜（SEM）对聚合物和复合材料进行了仪器分析。
