Аннотация: Nonwoven composite membranes based on polycarbonate (PC) and vinylidene fluoride/tetrafluoroethylene copolymer were obtained via the two-channel electrospinning method with a common collector. Three groups of materials were studied: the first one was a polymer membrane made of a vinylidene fluoride/tetrafluoroethylene copolymer, the second one was a polymer membrane based on PC, and the third one involved a composite polymer membrane. Scanning electron microscopy studies of morphology of the polymeric membranes showed that a composite material with a variable pore area could be obtained, which allows selection of this parameter depending on the purpose. The resulting composite material and its constituents are studied with nuclear magnetic resonance, IR spectroscopy, X-ray diffraction, and differential scanning calorimetry. There are electrically active crystalline phases in the composite membranes. The obtained nonwoven composite membrane formed is presented as a two-phase system without any chemical interactions between the phases. © A.V. Alekseev, D.Yu. Dubov, M.R.
