▎ 摘　　要

NOVELTY - Composition comprises graphene sheets, at least one binder, and at least one polyalkylene imine. USE - The composition is useful for coating a substrate including e.g. glass, lens (all claimed), flexible and/or stretchable materials, metals, fabrics and textiles (e.g. cotton, wool, polyesters and rayon), ceramics, silicon surfaces, wood, paper, cardboard, paperboard, cellulose-based materials, glassine, labels, silicon and other semiconductors, laminates, corrugated materials, concrete, bricks and other building materials, and electronic devices (e.g. cellular telephones, computers, personal digital assistants and global positioning system). ADVANTAGE - The composition utilizes graphene sheets having good adhesion to the substrates.
