Abstrakt: Properties of nonwoven materials based on copolymer of tetrafluoroethylene and vinyldenefluoride produced by aerodynamic formation in a turbulent gas flow are investigated in the paper. By means of scanning microscopy, it is shown that synthesized nonwoven materials are characterized by high porosity and complicated spatial organization. By means of X-ray diffraction, infrared spectroscopy, combination scattering spectroscopy, thermogravimetric analysis, and differential scanning calorimetry, it is shown that fibers that form the nonwoven material are characterized by a crystal structure typical of ferrielectric phases. The quantitative content of residual solvents in the formed materials is determined. By using a mobile cell culture, it is shown that the produced nonwoven materials are not toxic and can be used for medical purposes. [ABSTRACT FROM AUTHOR]
