▎ 摘 要
NOVELTY - Composition comprises graphene sheets and at least one acid. USE - The composition is useful as an ink or coating for coating an article (all claimed). ADVANTAGE - The composition: can be applied to the substrate in varying thicknesses at different points; can be used to form membranes having desired flow properties and porosities; and exhibit good surface resistivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an ink or coating comprising the composition; and (2) an article coated with the ink or coating.
