Nanocomposite thin-film structures based on a polyelectrolyte complex of chitosan and chitosan succinamide with SWCNT

The article is devoted to the study of nanocomposite thin films based on a polyelectrolyte complex chitosan and succinamide (PEC). Single-walled carbon nanotubes (SWCNT) were used as fillers. Using methods cyclic voltammetry electrochemical impedance spectroscopy, it was found that have larger effective surface area electron transfer rate compared films, which allows them be further in electroanalysis substances various nature. structure PEC with SWCNT using SEM showed there are formations form filaments formed by it. Studying nature morphology extremely important when creating sensory devices. Sensory sensitivity resistive thin-film structures air humidity ammonia vapors found. Based these materials, samples prepared, dependences flowing current relative concentration measured.
