摘要(Abstract)：

以脱脂棉、天丝和剑麻为原料，KOH溶液为活化剂，通过炭化、活化制备活性炭纤维（ACFs），研究炭化温度和碱碳比对ACFs物理化学性质的影响，并借助比表面积测试（BET）、X射线衍射分析（XRD）等手段对纤维进行表征。结果表明，3种原料炭化致孔的难易程度为：脱脂棉>剑麻>天丝。当炭化温度为700℃时，炭化材料的比表面积分别为390.4、48.8和179.2 m²×g^-1。采用质量分数w为10%的KOH溶液活化，碱碳质量比为2：1，脱脂棉、剑麻基ACFs的比表面积分别为1 375和1 161 m²×g^-1。采用w为20%的KOH溶液活化，当碱碳质量比为3：1时，天丝基ACFs的比表面积可达1 594 m²×g^-1，孔径分布比前两者窄。
