Electrospun carbon nanofibers (CNFs) are an excellent material which can possess a wide range of properties through controlling the parameters of the electrospinning process, as well as through thermal treatment. At the same time, CNFs are an excellent substrate for carrying out modifications, both volumetric, at the stage of precursor preparation, and surface modifications. Different methods of introducing various silicon carbide (SiC) precursors into the spinning solution enables the formation of needleshaped SiC nanostructures on the CNF surface. This work presents an attempt to obtain nanofibrous carbon materials modified in volume and on the surface with SiC precursors, along with their characteristics. The most promising method of creating needle-like SiC nanostructures on the surface of CNFs is the use of volume modification with polysiloxane and silanization of the surface of the CNFs in a organosilicon sol solution.
