摘要

以聚丙烯腈（PAN）为原料，分别加入0、2.5、5%和10%的聚乙烯吡咯烷酮（PVP），采用溶液吹丝法（SBS）制备了碳纤维。将纺丝纤维在管状烘箱中碳化，随后通过x射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、拉曼光谱（Raman）、碳氮元素分析和扫描电子显微镜（SEM）观察其微观结构特性。此外，还进行了电化学测试，包括动电位法、电位法和循环伏安法，以评估析氢反应（HER）。光谱表征表明，碳纤维是由SBS制备的。此外，还可以通过控制HER来抑制铅酸电池的析氢。

Carbon Fibers from PAN/PVP Blends by Solution Blow Spinning to Suppress Hydrogen Evolution in Lead-Acid Batteries.

In this work, carbon fibers were produced using the solution blow spinning (SBS) technique from polyacrylonitrile (PAN) blended with 0, 2.5, 5, and 10% of poly(vinylpyrrolidone) (PVP). Spun fibers were carbonized in a tubular oven and subsequently characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, carbon-nitrogen elemental analysis, and scanning electron microscopy (SEM) to observe their microstructural properties. Additionally, electrochemical tests, including potentiodynamic, potentiometric, and cyclic voltammetry, were conducted to evaluate the hydrogen evolution reaction (HER). Spectroscopic characterizations indicated that carbon fibers were produced by SBS. Moreover, it was possible to control the HER to suppress hydrogen evolution in lead-acid batteries.
