Abstract

One of the current areas of creating new types of materials with unique properties for use in various fields of human activity is nanotechnology. The article is devoted to the development of a two-layer material for use in surgery, where a soluble film acts as an anti-adhesion membrane and a nanofibrous coating provides a hemostatic effect. The aim of the study was to determine the optimal modes of nanofibers electrospinning on the soluble film using various types of substrates. During studies conducted on the electrospinning machine Fluidnatek LE-50, nanofibers were produced from solution of polyvinyl alcohol (PVA) with the addition of aluminum chloride on the film composed of PVA, glycerin, and gelatin. Three types of substrates were used to fix the film on the machine collector. Regression models were obtained that describe the effect of the emitter and collector potentials and the distance between them on the consumption of the spinning solution at which the electrospinning process was stable. Optimal parameters of the electrospinning process were determined when using each of the studied substrates. It was found that using matte polyvinyl chloride films as substrates, the optimal electroforming process is achieved by decreasing the distance between the emitter and collector while simultaneously increasing the difference in their potentials compared to using siliconized paper as a substrate.
