in-plane defects produced by ball-milling of expanded graphite

Aug 27, 2010 · Expanded graphite (EG) was ball-milled in a high-energy planetary-type mill under air atmosphere. The products were characterized by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). During the milling process (up to 100 h), the crystallite size (Lc) of EG decreases gradually from 15.4 to 11.3 nm

anti-friction effect of ball-milled expanded graphite/ni

A mixture of expanded graphite (EG) and nickel was ball-milled in a high-energy mill. The ball-milled EG-Ni mixtures were characterized by X-ray diffraction and their anti-friction effects used as lubricating additive were investigated. The results show that the mixtures have an obvious anti-friction effect

expanded graphite - an overview | sciencedirect topics

Expanded graphite is multi-porous (2–10 nm) and average pore size of ~2 mm. This form of graphite can be readily intercalated and host molecules including monomers and polymers can be incorporated between the expanded graphene sheets to form modified composite structure. EG has been developed as polymer reinforcement in early 1900s
