NOVELTY - Nano-graphene platelet-based conductive ink that is printable, comprises: pristine nano-graphene platelets, where each of the platelets has never previously been oxidized and comprises graphene sheet(s), and the platelets have an average thickness of not greater than 100 nm; and a liquid medium in which the nano-graphene platelets are dispersed, where the nano-graphene platelets occupy a proportion of at least 0.001 vol.% based on the total ink volume, and the ink is formulated so that it is capable of being printed in patterns by means of ink jet printing or screen printing. USE - The ink is useful: for printing on a substrate used in a patterned RFID device; for coating a thin film, flexible substrate or paper for electromagnetic interference shielding or electrostatic charge dissipation applications; and in a thermal interface material (all claimed). ADVANTAGE - The printed ink: has a thermal conductivity greater than 10 W/mK; utilizes nano-graphene platelets having ultra-high thermal conductivity and which are much less expensive than nano-silver particles (e.g. for RFID antenna application) and carbon nanotubes; and utilizes nano-graphene platelets-based nanocomposites which are capable of readily forming the thin film, paper or coating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a patterned RFID device comprised of the ink printed on a substrate; (2) a thin film, flexible substrate or paper coated with the ink, where the ink is patterned; and (3) a thermal interface material comprising the ink, where the ink is printed onto a plastic, elastomer or metal substrate, and the substrate may be planar or non-planar, and the printed ink has a thermal conductivity greater than 10 W/m.K.
