摘要

研究了非取代咪唑基质子离子液体,即咪唑硫酸氢[Imi][HSO4]作为聚苯胺(简称PANI/PIL)的聚合介质。然后研究了所得材料作为超级电容器的电极材料。通过一步酸碱反应制备了[Imi][HSO4],并通过1H NMR对其结构进行了证实。[Imi][HSO4]由于其离子的电荷密度分布,与水表现出完全的混溶性。此外,[Imi][HSO4]/水二元混合物呈强酸性(如[Imi][HSO4]/水在70/30的质量比下pH ~ 0.1)。[Imi][HSO4]作为聚苯胺/PIL的聚合介质,起到软模板剂的作用,在不影响聚苯胺典型结构的情况下,诱导形成具有纤维状形态的纳米结构聚苯胺(如SEM图像所示)(经FT-IR分析证实)。此外,聚苯胺/太平盐以翡翠盐的形式得到,没有任何不良的副产物。此外,用四探针法测定的电导率(~ 21.8 S/cm)比传统聚苯胺(即聚苯胺/盐酸)高7倍。PANI/PIL的电导率和纤维状形态的改善对其电化学性能产生了积极的影响,并突出了[Imi][HSO4]作为PANI材料聚合介质的适用性。

Nanostructuring Polyaniline Using Non-Substituted Imidazolium-Based Ionic liquid as Polymerization Medium Enabling Faster Supercapacitor Operation
Non-substituted imidazolium-based protic ionic liquid, namely imidazolium hydrogen sulfate [Imi][HSO4], has been investigated as a polymerization medium for PANI (designated as PANI/PIL). The resulting material was then investigated as electrode materials for supercapacitors. [Imi][HSO4] was prepared via a one-step acid-base reaction, and its structure was confirmed by 1H NMR. [Imi][HSO4] displayed full miscibility with water owing to the charge density distribution of its ions. Furthermore, the binary mixture [Imi][HSO4]/water is highly acid (e.g. pH ~ 0.1 for [Imi][HSO4]/water in a weight ratio of 70/30). As the polymerization medium for PANI/PIL, [Imi][HSO4] plays the role of a soft template agent and induces nanostructured PANI formation with fibrillar morphology (as shown by SEM images) without affecting the typical structure of PANI (as confirmed by FT-IR analysis). Furthermore, PANI/PIL was obtained in emeraldine salt form without any undesirable byproduct. Moreover, the electrical conductivity was seven times superior to that of the conventional PANI (i.e. PANI/HCl) when measured by the four-probe technique of PANI/PIL (~ 21.8 S/cm). This improvement in the PANI/PIL’s electrical conductivity of as well as the fibrillar morphology of PANI/PIL positively influences its electrochemical performances and highlights the suitability of [Imi][HSO4] as a polymerization medium for PANI material.
