摘要：

The relation between the in-plane orientation of polyimide film and graphitizability was investigated. The degree of in-plane orientation was estimated by means of optical birefringence and ESR technique. The polyimide film was found to have non-uniform orientation in the thickness direction because the thinner the film was, the greater the orientation. The inhomogeneity of orientation caused multiphase graphitization in a film with a composite profile of the X-ray diffraction peak.
