| 摘 要： | 将PAN坝氧化纤维在400℃～900℃炭化，经CO2活化得到一系列活性炭纤维，表征了其比表面、孔容和孔径分布等微结构参数，研究了炭化温度对CO2活化PAN基活性炭纤维微结构的影响。结果表明，炭化温度对活性炭纤维的比表面和孔结构有显著影响，适中的炭化温度（600℃）有利于得到高比表面积、大的孔容和孔径。 |

| Abstract: | A series of activated carbon fibers (ACFs) was prepared by carbonizing pre-oxidized PAN fibers at temperatures ranging from 400 to 900 ℃ followed by CO2 activation and the effect of carbonization temperature on the porous structure of polyarcylonitrile (PAN)-based ACFs characterized by nitrogen adsorption was investigated. It is found that the porous structure of PAN-ACF depends strongly on the carbonization temperature, and a moderate carbonization temperature (600 ℃ ) is favorable to obtain ACFs with higher specific surface area, larger pore volume and larger pore size. |
