Title:
TWO-DIMENSIONAL PARTICLE, ELECTRICALLY CONDUCTIVE FILM, ELECTRICALLY CONDUCTIVE PASTE, AND METHOD FOR PRODUCING TWO-DIMENSIONAL PARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/048081
Kind Code:
A1
Abstract:
A purpose of the present disclosure is to provide a two-dimensional particle able to provide an electrically conductive film that can maintain high electrical conductivity even under conditions of high humidity. Another purpose of the present invention is to provide a method for producing said two-dimensional particle. This two-dimensional particle has one or more layers and contains a metal cation. Said layer contains: a layer main body represented by formula: MmXn (in the formula, M is at least one type of group 3, 4, 5, 6 or 7 metal, X is a carbon atom, a nitrogen atom or a combination of these, the value of n is 1-4, and the value of m is greater than the value of n and is 5 or less); and a modification or a terminal T that is present at the surface of the layer main body (T is at least one type selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom and a hydrogen atom). Either the modification or terminal T contains a chlorine atom or M in the layer binds to at least one type selected from the group consisting of PO4 3-, I and SO4 2-. The metal cation includes at least one type of cation of a metal in the 3rd to 5th periods of the periodic table. The content of Li is less than 0.002 mass%.
