FTIR spectra of a dehydrofluorinated poly(vinylidene fluoride) film were registered at different stages of its aging. A number of spectral features were noticed to grow with the sample aging. Three of them were assigned to the stretching vibrations o

XPS of partially crystalline PVDF film have been studied in the course of carbonization under Al Kα radiation. The long-term exposure of PVDF film and enhancement of the spectra resolution allowed further refinement of the previously proposed degrad

Under the action of ionizing radiation on a PVDF film, fluorine and hydrogen atoms bound to its linear carbon chain with single chemical bonds detach. Free atoms and HF molecules diffuse toward the film surface and escape from it. As a result of irra
