Evolution of crystalline phases of P(VDF-TeFE) films filled with nanographite in various aprotic solvents

The work under discussion describes the preparation and study copoly(vinylidene fluoride–tetrafluoroethylene) (P(VDF–TFE)) films filled with chemically exfoliated nanographite and crystallized by drying from various solvents. The  content of α, β and γ phases of PVDF was estimated via Fourier transform infrared spectroscopy (FTIR) and supported by Raman spectroscopy and X-ray diffractometry. Experimental study revealed that films made from a solution of  dimethyl sulfoxide (DMSO) have a higher content of the polar β-phase and films filled with nanographite showed increased degree of of β-phase content.
