A patent application (Publication Number: US20240034634A9) discloses a conductive two-dimensional particle made of a layered material with specific characteristics. The particle includes a layer body represented by MmXn, where M is a metal from Group 3, 4, 5, 6, or 7, X is a carbon atom, a nitrogen atom, or a combination, n is 1 to 4, and m is more than n and 5 or less. The particle also contains a modifier or terminal T on the surface, such as a hydroxyl group or a fluorine atom, and a monovalent metal ion, with specific limitations on the content of chlorine and bromine. The particle's major diameter ranges from 1.0 µm to 20 µm, and its thickness averages between 1 nm to 10 nm.

Furthermore, the patent application describes methods for producing these conductive two-dimensional particles, involving the preparation of a precursor, etching processes, and intercalation treatments with monovalent metal ions and organic compounds. The method aims to create particles with specific characteristics suitable for use in conductive pastes and composite materials. The inclusion of specific metal compounds containing monovalent metal ions, such as lithium, and organic compounds with defined dissolution parameters is crucial in the production process. Additionally, delamination treatments may be performed to further enhance the properties of the particles. Overall, the patent application outlines a detailed process for creating unique conductive two-dimensional particles with potential applications in various industries.
