Abstract

In this study, activated carbon fibers (ACFs) were prepared using a new method from polyethylene (PE) fibers. The stabilizing (or crosslinking) process of PE, an essential step, was achieved through a hybrid treatment using electron-beam/sulfuric acid at 110 °C that was more effective than the traditional method of using sulfuric acid at 180 °C for polyolefin. The stabilized precursor was then carbonized at 700 °C and activated at 900 °C with different activation times. The structural characteristics and morphologies of these ACFs were observed using an X-ray diffractometer and a field-emission scanning electron microscope, respectively. In addition, the N/77K adsorption isotherm was used to discern textural properties. The total pore volume and specific surface area of these ACFs were found to be increased with a longer activation time, reaching final values of 0.99 cm/g and 1750 m/g, respectively. These ACFs also exhibited a high mesopore volume ratio (39%) according to crosslinking and crystallite formation conditions.

摘要

在本研究中，采用一种新方法由聚乙烯（PE）纤维制备了活性炭纤维（ACF）。PE的稳定化（或交联）过程是一个关键步骤，通过在110℃下使用电子束/硫酸的混合处理实现，该方法比在180℃下对聚烯烃使用硫酸的传统方法更有效。然后将稳定化的前驱体在700℃碳化，并在900℃下以不同的活化时间进行活化。分别使用X射线衍射仪和场发射扫描电子显微镜观察这些ACF的结构特征和形貌。此外，采用N/77K吸附等温线来识别织构性质。发现这些ACF的总孔体积和比表面积随着活化时间的延长而增加，最终分别达到0.99 cm/g和1750 m/g。根据交联和微晶形成条件，这些ACF还表现出较高的中孔体积比（39%）。
