▎ 摘  要

NOVELTY - Nano-scaled graphene platelet (I) having a length, a width, and a thickness, is claimed, where the thickness is not greater than 100 nm and the length-to-width ratio is not less than 3. USE - (I) is useful for the preparation of the composite material (claimed), which is useful for shielding of sensitive electronic equipment against electromagnetic interference or radio frequency interference and for electrostatic charge dissipation. (I) is useful as reinforcement filler in a structural composite. ADVANTAGE - (I) has: high length-to-width ratio (greater than 3, preferably greater than 10); high length-to-thickness ratio (at least 10000, preferably at least 30000); and thickness (thinner than 10 nm, preferably thinner than 1 nm). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nanocomposite material comprising (I) dispersed in a matrix material, where the matrix material has a weight fraction of 1-99% of the nanocomposite.
