Abstract

Poly(3-methyl thiophene) nanospheres with their size ranging around 50-60 nm have been synthesized by simply adding monomers into a magnetic ionic liquid, Bmim[FeCl(4)]. The ionic liquid leads to the formation of uniform nanospheres with a relatively narrow size distribution confined to submicrometer-sized domains. The poly(3-methyl thiophene) nanospheres were characterized by FTIR, Raman and thermogravimetric analysis (TGA). Scanning electron microscopy (SEM) was used to show the morphology of the samples. As compared with the conventional solution polymerization method, the polymerization yield and conductivity of the polymers produced in this magnetic ionic liquid system were improved.

摘要

通过简单地将单体添加到磁性离子液体Bmim[FeCl₄]中，合成了尺寸在50 - 60纳米左右的聚（3 - 甲基噻吩）纳米球。该离子液体导致形成尺寸分布相对较窄的均匀纳米球，其尺寸限制在亚微米级区域。通过傅里叶变换红外光谱（FTIR）、拉曼光谱和热重分析（TGA）对聚（3 - 甲基噻吩）纳米球进行了表征。使用扫描电子显微镜（SEM）来展示样品的形态。与传统的溶液聚合方法相比，在这种磁性离子液体体系中制备的聚合物的聚合产率和电导率都得到了提高。
