采用红外光谱（FTIR）及X光电子能谱（XPS），系统分析了纤维碳化各阶段的结构、不同程度活化的ACF的结构以及低温氧化后和热处理后ACF的结构，提出了ACF表面结构模型。
The structure of ACF at various stages of fiber carbonization, the structure of ACF activated at different degrees and the structure of ACF after low temperature oxidation and heat treatment were systematically analyzed by FTIR and XPS. The ACF surface structure model was proposed.
