A sustainable and green method is presented in this paper to produce highly oxidized carbon black using dry ball milling. The mechanical energy by colliding milling balls is able to easily break and build chemical bonds providing new oxygenated functional groups. The reaction is performed in the presence of air and in solventfree conditions achieving, for the first time, a high degree of ...
