Usage composite ferroelectric membranes for healing of purulent wounds in the experiment

Abstract

The paper contains the results of an experimental study of the effect of ferroelectric composite polymer membranes on the healing process of purulent wounds. The membranes were formed by electrospinning based on vinylidene fluoride-terafluoroethylene copolymer, polyvinylpyrrolidone K17 (PVP) polymer, zinc oxide nanoparticles (ZnO). Five spinning solutions with different contents of PVP were prepared: 0, 5, 10, 20 and 40 mass %.The effect of the membranes was evaluated depending on the content of PVP. The conductivity and viscosity ofthe spinning solutions were determined. The structure of the formed membranes was studied. The diameter of the fibers forming the membranes was determined by scanning electron microscopy. The antibacterial activity of the membranes was evaluated. The ability of the developed membranes to heal a purulent wound was studied in experiments on laboratory animals.
