摘要： A dispersion of nanoplatelets or particles suspended in a carrier liquid is disclosed. The nanoplatelets or particles, e.g. graphene nanoplatelets, are derived from a layered material. The loading amount of nanoplatelets or particles in the dispersion is at least 20 mg nanoplatelets or particles per 1 ml of dispersion. The dispersion optionally further including a dispersant, the volume ratio of dispersant to the nanoplatelets or particles being less than 1:1. A process for manufacturing the dispersion includes mixing the carrier liquid and the nanoplatelets or particles under high shear conditions. The dispersion can be used as an ink system, as a functional additive within an ink, coating or adhesive formulation, and/or in the manufacture of a nanoplatelet-polymer composite or a particle-polymer composite.

摘要： An ink disclosed herein comprises a carrier liquid with a dispersion of flakes derived from a layered material. The thickness of each flake depends on the number of layers of the layered material in the flake. The thickness distribution of the flakes includes: at least 20% by number of single layer flakes; at least 40% by number cumulatively of single, double and triple layer flakes; or not more than 40% by number of flakes having ten or more layers. The layered material is selected from one or more of elemental materials such as graphene (typically derived from pristine graphite), metals (e.g., NiTe2, VSe2), semi-metals (e.g., WTa2, TcS2), semiconductors (e.g., WS2, WSe2, MoS2, MoTe2, TaS2, RhTe2, PdTe2), insulators (e.g., h-BN, HfS2), superconductors (e.g., NbS2, NbSe2, NbTe2, TaSe2) and topological insulators and thermo-electrics (e.g., Bi2Se3, Bi2Te3). Also disclosed are methods of manufacturing suitable inks and uses of the inks.
