Synthesis of Carbon Nanotubes by the Electric Arc-Discharge Method

“…Currently, the synthesis of CNTs is based on the methods of thermal plasma [17], chemical vapor deposition (CVD) [18] and arc discharge [19]: Tian et al [14] were the first to develop a thermal plasma method for obtaining multi-walled CNTs (MWCNTs) from coal, the second one based on the thermal decomposition of carbon-containing gases (chemical vapor deposition), accompanied by gas-phase chemical deposition (GPCD) of crystalline nanocarbon on metal catalysts. The third method of synthesis consists in the evaporation of graphite and the subsequent condensation of the product when the vapor is cooled in an arc discharge.…”

Production of Carbon Fibers by Electrospining Method

“…Among a wide class of nanomaterials, carbon fibers (CF) occupy a separate position, due to the uniqueness of their physicochemical properties and the prospects for practical application [1]. Carbon nanofibers (CNF) are a class of materials in which curved graphene layers or nanocones are composed in the form of a quasi-one-dimensional filament whose internal structure can be characterized by an angle α between the layers of graphene and the fiber axis [2].…”
