Влияние вязкости и электропроводности прядильных растворов на структуру мембран из политетрафторэтилена изготовленных методом электроспиннинга

Abstract

This work presents the results of a study of the influence of viscosity and electrical conductivity of spinning solutions on the morphology of porous polymeric membranes made of polytetrafluoroethylene fabricated via electrospinning. Scanning electron microscopy has demonstrated that the viscosity and electrical conductivity of spinning solutions are the main technological parameters that make it possible to effectively control the average diameter of fibers in polytetrafluoroethylene membranes. It is shown that such parameters as the absorption of the liquid wetting the membrane, the apparent density and open porosity of the formed membranes do not depend on the viscosity and electrical conductivity of the spinning solutions and the average diameter of the fibers in the membranes.
