- Аннотация: Biocompatible electrically conducting chitosan-based films filled with single-wall carbonnanotubes were obtained. Atomic force microscopic studies of the free surface topography revealed achange in the morphology of chitosan films filled with single-wall carbon nanotubes. Introducing0.5 wt.% of single-wall carbon nanotubes into chitosan results in an increase in tensile strength ofthe films (up to ~180 MPa); the tensile strain values also rise up to ~60%. It was demonstrated thatchitosan films containing 0.1–3.0 wt.% of single-wall carbon nanotubes have higher conductivity(10 S/m) than pure chitosan films (1011 S/m). The investigation of electrical stimulation of humandermal fibroblasts on chitosan/single-wall carbon nanotubes film scaffolds showed that the biologicaleffect of cell electrical stimulation depends on the content of single-walled carbon nanotubes in thechitosan matrix.
