摘　　要：采用XPS表面分析技术测试了预氧丝、炭纤维、活性纤维(ACF)的表面元素含量及其结合态,对炭化活化过程中各元素结合态的变化进行了分析。发现预氧丝中的O、N结合态较单一,而C、O、N在ACF中以多种结合态形式存在,活化过程并不明显增加表面含氧基团的数量。The element contents, binding forms and surface functional groups of preoxidized fiber, carbon fiber and activated earbon fiber were investigated with XPS. The results showed that O &-N had multiple binding forms in ACF in contrast to the unities in POF. The increasement of oxygen-containing groups wasn't found after activation process.
