Graphene-like films from carbon black: a facile and convenient route

Aim of this study is to propose a convenient synthesis of graphene-like films starting from water suspension of oxidized carbon black (CB). The selected oxidative treatment provides the partial demolition of the CB microstructure and the functionalization at the edge of the basal planes of the graphitic layers [4] and not on them. In this way, differently from GO, the oxidized CB preserves the original graphitic network useful for the conductivity and electronic properties. The method offers scalability and potential high-volume production of graphene-like films at reduced costs.
