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.

Graphene compositions

A method of coating a substrate wherein a composition comprising graphene sheets and at least one polymer having a melting point or glass transition temperature of no greater than about 100&#xb0; C. is applied to the substrate and the composition is cured at a temperature no greater than about 135&#xb0; C. to form a coating.

Method of coating a substrate with a graphene containing composition

A method of printing articles having variable conductivities, including those having conductivity gradients.

Method of printing a conductive article and articles made thereby

Compositions comprising graphene sheets, at least one binder, and a carrier system, wherein about 1 to about 50 weight percent of the carrier system comprises at least one cyclic amide, cyclic imide, and/or lactone. The compositions may be used as coatings and inks.
