The present disclosure relates to wet-milled and dried carbonaceous sheared nano-leaves generally characterized by a BET SSA of less than about 40 m2/g and a bulk density from about 0.005 to about 0.04 g/cm3, and compositions comprising such carbonaceous sheared nano-leaves. The present disclosure further relates to methods for preparing them, and their use as a conductive additive in composites such as polymer blends, ceramics, and mineral materials, or as solid lubricant. La présente invention concerne des nano-feuilles cisaillées carbonées humides et séchées généralement caractérisées par une surface spécifique BET d'environ moins de 40 m2/g et une masse volumique d'environ 0.005 à environ 0.04 g/cm3, et des compositions comprenant de telles nano-feuilles cisaillées carbonées. La présente invention concerne en outre des procédés de préparation de ceux-ci, et leur utilisation en tant qu'additif conducteur dans des composites tels que des mélanges de polymères, des céramiques et des matériaux minéraux, ou en tant que lubrifiant solide.
