N2 - In this work, hybrid polymer fiber membranes based on polyvinylidene fluoride (PVDF) with graphite flakes were obtained by electrospinning. The morphology of the obtained samples was investigated using SEM microscopy methods, and their crystalline structure was analysed using XRD, Raman, and FTIR methods. Using RFE spectroscopy, it was shown that the addition of graphite leads to ion-dipole interaction between the carbon surface and the polymer dipoles, changing the ratio of covalent and semi-ionic bonds on the surface. The catalytic properties investigated during the decomposition of the organic dye methylene blue (MB) demonstrated high piezocatalytic activity of doped membranes and high photocatalytic activity of PVDF/C0.5. It was established that the photocatalytic activity is due to excitonic excitation.
