In this study, we demonstrate the fabrication of an electrochemically active nanofiber mat that is a composite of high‐performance poly(imide sulfonate) (PIS) and polyaniline (PANI). First, a nonconductive nanofiber mat comprising nanofibers having diameters of ca. 300 nm was fabricated by the electrospinning of ionomeric PIS in N,N‐dimethylformamide (DMF). Then, the nanofibers were modified using PANI, which was synthesized by the oxidative polymerization of aniline, yielding an electrochemically active nanofiber mat having a diameter of ca. 350 nm. It was confirmed that PANI was successfully incorporated onto the PIS nanofiber mats by X‐ray photoelectron spectroscopy. Subsequently, we conducted electrochemical measurements of the PANI‐modified nanofiber mats using a tailor‐made attachment in which the working electrode gently comes in contact with the nanofiber mat surface. This attachment was observed to be widely useful in the cyclic voltammetry measurements related to redox‐active nanofibers. These observations are expected to contribute to the advancements in application development of the electrochemically active nanofiber mats.

含聚酰亚胺磺酸盐的聚苯胺氧化还原活性纳米纤维毡的制备和电化学仪器

在这项研究中，我们演示了电化学活性纳米纤维垫的制造，该垫是高性能聚酰亚胺磺酸盐（PIS）和聚苯胺（PANI）的复合材料。首先，一种非导电纳米纤维垫，其包括直径为约1μm的纳米纤维。通过离聚物PIS在N，N-二甲基甲酰胺（DMF）中的电纺丝制造300 nm。然后，使用PANI对纳米纤维进行改性，该PANI是通过苯胺的氧化聚合而合成的，从而制得了直径为约50μm的电化学活性纳米纤维垫。350纳米 通过X射线光电子能谱证实，PANI已成功整合到PIS纳米纤维垫上。随后，我们使用量身定制的附件对PANI改性的纳米纤维垫进行了电化学测量，其中工作电极与纳米纤维垫表面轻轻接触。据观察，这种附件在与氧化还原活性纳米纤维有关的循环伏安法测量中广泛有用。预期这些观察将有助于电化学活性纳米纤维垫的应用发展。
