Abstract

Carbon nanotubes (CNTs), due to their uniquemorphology and physico-chemical properties, arepotentially useful in nanotechnology, electronics, opticsand other fields of material science. However, their useis limited by their sensibility to oxidation, especially athigh temperatures. Chemical resistance of CNTs could be increased by coating with non-oxide, e.g. BN layers.The aim of the present work was to study theformation of boron nitride thin films on CNTs bythermal treatment. The role of the surface compositionof the CNTs was also investigated. Prior to the laboratory experiments, thermodynamic calculationswere performed to determine the optimum BNformation temperature and composition of the startingmaterials and reagents.Thin films of boron nitride were deposited on CNTssurfaces by mixing with boric acid solutions, drying andnitriding in an ammonia flow at 1050 °C. The productswere analysed by XPS for the surface chemical composition and BN coverage, and TEM morphology.Resistance of the coated CNTs against high temperature oxidation was tested by the thermal analysis (TGA) method. As a result, BN coverage on the nanotubes andan increased oxidation resistance was achieved.
