Abstract

Compositions comprising graphene sheets, graphite, at least one binder, a carrier system. About 1 to about 50 weight percent of the carrier system comprises at least one of a cyclic imide and lactone. The graphene sheets consist of fully exfoliated single sheets of graphite. The ratio by weight of graphite to graphene sheets is from about 50:50 to about 85:15. The composition may be used as coatings and inks.
