Abstract |
Carbon Black(CB) is obtained from the partial combustion or thermal decomposition of hydrocarbons. Its primary particles exhibit a spherical shape which form aggregates. The aggregates are further agglomerate because of strong van der Waals forces among the surface of the CB nano particles. These material depends on its dispersion, however, it exhibits a strong tendency to agglomerate, and the preparation of a stable dispersion of the material in organic solvents or in polar solvents such as water. This experiment describes the results of reacting dialkylamines with carbon black that had been oxidized in nitric acid for varying times. Reacting alkylamine groups with oxidized carbon black could introduce several amino functions for each carboxyl group consumed. In this way the total amount of available surface-bound functional groups could be increased. Therefore, the dispersions of the modified CB was stable in organic solvents and water base.
