活性炭纤维在后炭化过程中变化较大。研究了不同温度下孔结构和表面性质的变化。在不同的温度下，发生不同的后炭化过程。低温（923 K）时，孔结构变化不大，表面酸性明显增加。而在较高温度（1123 K）下，孔结构发生了较大的变化，表面呈现出相对于农化PAN基ACE的碱性。总之，不同的后炭化工艺会带来不同的性能，这有助于开发具有不同功能的新型活性炭纤维。
ACF changes greatly during post-carbonization. The changes of pore structures andsurface properties were investigated under different temperamre. At the different temperature,different post-carbonization process takes place. At the low temperature (923 K) the porestructure makes little change and the acidity of the surface increases obviously. While at thehigher temperature (1123 K) the pore structure changes soundly, the surface shows base propertyrelative to the rural PAN-based ACE In short, different post-carbonization processes bring ACFsdifferent properties, which help to the development of the novel ACFs with different functions.
