Abstract

The purpose of this study was the polymerization of carbazole (Cz), pyrrole (Py) and copolymerization of them onto polyester (PES) textile with chemical oxidative method by using FeCl₃. First, in order to determine the optimum conditions, the effect of polymerization steps, the immersion order of the PES to the oxidant and monomer solutions, time, monomer, oxidant, and surfactant concentrations and types on the conductivities of PES/PCz composite were investigated and at this conditions, conductive composite, PES/P[Py-co-Cz] was obtained. The highest conductivities were obtained as 12.4 mS/cm and 9.0 mS/cm for PES/PCz and PES/P[Py-co-Cz], respectively. Further characterization of PES/P[Py-co-Cz] was performed by conductivity, FTIR, scanning electron microscopy (SEM), and dynamic mechanical analysis (DMA) measurements, and results were compared with PES/PCz and also PES/PPy. The presence of Py and Cz in the same polymer chain created synergy and improved the conductivity and mechanical properties of the composite.

将吡咯和咔唑共聚到聚酯织物上。

本研究的目的是采用化学氧化法，利用 FeCl3 将咔唑（Cz）、吡咯（Py）及其共聚物聚合到聚酯（PES）纺织品上。首先，为了确定最佳条件，研究了聚合步骤、PES 对氧化剂和单体溶液的浸入顺序、时间、单体、氧化剂和表面活性剂的浓度和类型对 PES/PCz 复合材料电导率的影响，并在此条件下获得了导电复合材料 PES/P[Py-co-Cz]。PES/PCz 和 PES/P[Py-co-Cz]的最高电导率分别为 12.4 mS/cm 和 9.0 mS/cm。通过电导率、傅立叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和动态机械分析（DMA）测量对 PES/P[Py-co-Cz]进行了进一步表征，并将结果与 PES/PCz 和 PES/PPy 进行了比较。在同一条聚合物链中含有 Py 和 Cz 产生了协同作用，提高了复合材料的导电性和机械性能。
