Effect of thermal oxidative treatment on the structure and electrical conductivity of nanodispersed carbon black particles

The effect of thermal oxidative treatment on the structure and electroconductive properties of the particles of globular nanodispersed carbon (GNDC, carbon black) was demonstrated. The comprehensive study of the structure of GNDC particles was performed by Raman spectroscopy, X-ray diffraction (XRD) analysis, and high-resolution transmission electron microscopy (HR TEM) in comparison that of foreign and domestic commercial electroconductive brands. A correlation between structure characteristics obtained by different methods and the final properties of test GNDCs was established. The interrelation between the electroconductive properties and the length of the graphene planes of primary GNDC particles was confirmed.
