Abstract
The carbon films prepared from polyimide Kapton were investigated by X PS and elemental analysis. The chemical states of carbon and nitrogen gradually changed with carbonization temperature and the changes in th e peak intensity ratio of I[N1s]/I[C1s] by XPS were consistent with N/ C mole ratios by elemental analysis. The N1s peak around 401 eV which was a main component at 1200 degrees C was considered to correspond to quaternary species such as a pyrrole type nitrogen. This species may exist in the carbon films prepared at 2000 degrees C and affect their properties. (C) 1997 Elsevier Science Ltd.
