摘要

Carbon materials should have specific centers for its functionalities. In this study, the specific centers of polybenzoxazine carbides were studied for the first time. Three classical benzoxazine monomers were chose as the object. The transformation of nitrogen configuration of polybenzoxazines carbides was characterized via pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and X-ray photoelectron spectroscopy (XPS). The results showed that the tertiary amine nitrogen converted to pyridinic nitrogen and pyrrolic nitrogen incorporated in graphene residuals during the carbonization, which were the specific centers for the functionality.
