Abstract: Currently, the development of composite and nanocomposite materials based on natural polymers attracts in creasing attention of scientists. This article discusses the studies of composite and nanocomposite thin-film structures based on chitosan succinamide obtained using various fillers, such as graphene oxide, single-walled carbon nano tubes and carbon adsorbents. Using atomic force microscopy, it was shown that composite sensors based on chitosan succinamide and various carbon-containing particles have a sufficient effective surface area and electron transfer rate, which allows them to be considered as highly promising materials for the creation of field-effect transistors in the future. The surface morphology of the films was also studied. Using a scanning electron microscope with soft ware, images of the surface of the polymers of interest were obtained. The results were used to create field-effect transistors based on the films under consideration as a transport layer. The mobility of charge carriers was assessed and the following values were obtained: μ(SCTS) = 0.173 cm2/V s; μ(SCTS-GO) = 0.509 cm2/V s; μ(SCTS-CP) = = 0.269 cm2/V s; μ(SCTS-CB) = 0.351 cm2/V s; μ(SCTS-SWCNT) = 0.713 cm2/V s.
