摘　　要：论文采用水蒸气物理活化、KOH化学活化结合的方式,在PAN基碳纤维上进行刻蚀,并利用扫描电子显微镜(SEM)、比表面积(BET)、碘吸附对纤维的微观结构、孔结构以及吸附性能进行分析。结果表明:二次活化制备的活性碳纤维碘吸附值可达1900 mg/g、比表面积可达2051.14 m2/g,具有较高的吸附性能,能够连续化生产制备。Activated carbon fibers were prepared by etching the carbon fibers by physical activation of water vapor and KOH chemical activation. The effects of KOH on the structure and adsorption properties of PAN-ACFs were studied by specific surface area (BET) measurements, scanning electron microscope (SEM) and iodine adsorption. The results show that the activated carbon fiber prepared by secondary activation has an iodine adsorption value of 1900 mg/g and a specific surface area of 2051.14 m2/g, which has high adsorption performance. It can be continuously produced.
