Abstract
The conducting film material intended for research in the field of cell technology is obtained on the basis of two biocompatible polymers—aliphatic copolyamide and polypyrrole. The material consists of hybrid nanofibers having the core–shell structure. The film is formed by copolyamide microfibers that are obtained by electrospinning and coated with a polypyrrole nanolayer. Studies show that the material is stable and does not change its characteristics when stored both in air and in aqueous media. The hybrid fiber film has a high porosity, good water wettability, and a sufficient level of stress–strain characteristics. The resistance of the material is 300–600 Ω/sq, which allows its use for the electrical stimulation of proliferative activity of cells.
