NEXAFS and XPS of partially crystalline PVDF film have been studied in the course of carbonization under synchrotron radiation. High quality NEXAFS spectra of partially degraded PVDF have been achieved using conducting glue which allows significant suppression of electrostatic charging of a polymer sample. Spectra shape and intensity evolution suggests destruction of CF 2 and CH 2 groups and formation of π bonds relevant to sp and sp 2 hybrid states of carbon atoms. XPS spectra show creation of CF groups and a variety of carbon atoms not attached to fluorine directly but having the nearest carbon neighbors covalently bonded with fluorine. |
