ball milling of graphite

The ball milling of graphite in the presence of a liquid leads to very thin, well-crystallized and anisometric particles. In the presence of water, the graphite particles are covered byγ Fe 2 O 3(maghemite) formed by the oxidation of the ferrous alloy coming from the milling tools.

Preparation of graphene via wet ball milling and in situ

Abstract Functionalizedgraphene(G-MA) was prepared by a facile wetball millingstrategy, which achieved exfoliation and functionalization ofgraphitesimultaneously. TheG-MAshowed excellent dispersion in water and polar solvents. Thus, aG-MA coatingwas prepared from G-MA in mixed solvents (H 2 O–ethanol) without binder or surfactant.

Ball millingof Fe 2 O 3 powder withoutgraphitewas also tested. While reduction to metallic iron was again successful, the iron particles in direct contact led to mm-scale iron fragments, shown in Supplementary Fig. 1. This demonstrates thatball millingalone is insufficient to produce nanoscale encapsulated particles.

Exfoliation of graphene sheets via high energywetmilling

Graphitelayers are arranged to form bulkgraphitevia weak forces that well known as Van der Waals forces. These weak forces may resist the exfoliation of graphene fromgraphiteviamillingprocess. The impact and shear forces generated via high energyball millingcan overcome the Van der Waals forces between thegraphitelayers.
