摘要：

Highly stable dispersions of graphite are obtained in water/acetone mixtures, while graphite precipitates promptly in water and in acetone. We found that acetone facilitates disintegration of the graphite particles and their aggregates during a sonication process Fine graphite particles are stabilised by the electrostatic repulsion due to negative charges on the graphite particle surfaces (C) 2010 Elsevier Inc All rights reserved.
