A paste that includes particles of a layered material in an ammonia aqueous solution. The particles include one or plural layers, the layers having a layer body represented by MX, wherein M is at least one metal of Group 3, 4, 5, 6, or 7, X is a carbon atom, a nitrogen atom, or a combination thereof, n is not less than 1 and not more than 4, and m is more than n but not more than 5, and a modifier or terminal T exists on a surface of the layer body, wherein T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom, and a hydrogen atom, wherein the paste has a viscosity of 1 Pa·s or more at a shear velocity of 1/s when the paste has a solid content concentration of 1.0% by mass.

Paste and conductive film and their production methods

A conductive two-dimensional particle of a layered material comprising one layer or one layer and plural layers, wherein the layer includes a layer body represented by: MX, and a modifier or terminal T exists on a surface of the layer body, wherein T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom, or a hydrogen atom, M of the layer is bonded to at least one selected from the group consisting of PO, I, or SO, the total content of chlorine and bromine is 1,500 ppm by mass or less, and an average value of major diameters of two-dimensional surfaces of the conductive two-dimensional particles is 1.0 μm or more.

Conductive two-dimensional particle and method for producing the same

A conductive material including a plurality of particles, the plurality of particles including at least a first particle having: a layered material including one or plural layers, wherein the one or plural layers include a layer body represented by MX(where M is at least one metal of Group 3, 4, 5, 6, or 7, X is a carbon atom, a nitrogen atom, or a combination thereof, n is not less than 1 and not more than 4, and m is more than n but not more than 5), and a modifier or terminal T (where T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom, and a hydrogen atom) existing on a surface of the layer body; and a metal material at least partially covering the layered material.
