Abstract
Herein, we report results of the study of the composite ferroelectric scaffolds based on vinylidene fluoride-tetrafluoroethylene copolymer (VDF-TeFE) and polyvinylpyrrolidone (PVP) produced by electrospinning and their application as a wound-healing material. The physicochemical properties of ferroelectric composite polymer scaffolds depending on the content of PVP (in the range from 0 to 50 wt %) including morphology, composition and crystalline structure were studied. The cytotoxicity of materials and the proliferative activity of cells during their cultivation on the surface of formed scaffolds are reported. It has been found that the optimal PVP content in the VDF-TeFE composite scaffolds is 15 wt%. On a model of a full-thickness contaminated wound in vivo, it was shown that piezoelectric scaffolds based on VDF-TeFE copolymer containing 15 wt% PVP provide better wound healing results in comparison with standard gauze dressings impregnated with a solution of an antibacterial agent.
