Oxidative modification of carbon nanofibers (CNFs) is performed using the following methods: ball milling followed by oxidation in air, treatment with a nitric acid solution, and electrochemical treatment with a solution of sulfuric acid. The changes in the properties of CNFs are monitored by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS). The effect of the method by which carbon nanofibers are treated on the thermal-oxidative stability of epoxy composites containing the initial or modified CNFs is established.
