【摘要】 研究了活性炭纤维在氟化前后的结构与性能的变化。结果表明,随着反应时间和温度的变化,活性炭纤维表面氟取代氢基数目增加,同时在分子水平上形成C—F共价键。氟化后活性炭纤维的孔结构和比表面积变小,氮低温吸附等温曲线明显降低。更多还原

【Abstract】 The structures and properties of activated carbon fibers were studied at fluorination before and after. The results show that the hydrogen of C—H bond on ACFs were substituted by fluorine at different condition. The C—F covalence bond was built at molecular level. The pore size and specific surface area of ACFs were decreased after fluorination. The adsorption isotherm of nitrogen on ACFs were evidently reduced.更多还原
