Abstract: Provided is a composite material that has improved dispersibility of an exfoliated layered substance in a resin or the like and can thus significantly improve the properties, such as impact resistance, of a synthetic resin. A composite material in which the surface of an exfoliated layered substance is coated with a compound having a reactive group, wherein the compound having a reactive group is a compound having at least one reactive group selected from the group consisting of an epoxy group, an oxetanyl group, an isocyanate group, an acrylic group, a methacrylic group, a vinyl ether group, a vinyl ester group, and a hydrolyzable silyl group, and the compound having a reactive group is contained in an amount of 0.1 to 100 parts by mass, with respect to 100 parts by mass of the exfoliated layered substance.

Abstract: Provided is a method for producing a composite material in which the dispersibility of an exfoliated layered substance in a resin or the like is improved and with which a synthetic resin having significantly improved properties, such as impact resistance, can be obtained. A method for producing a composite material including an exfoliated layered substance and a coating substance coating a surface of the exfoliated layered substance includes a disintegrating step of disintegrating secondary particles of an exfoliated layered substance in a solution containing a coating substance, or a method for producing a composite material including an exfoliated layered substance and a coating substance coating a surface of the exfoliated layered substance includes a disintegrating step of disintegrating secondary particles of an exfoliated layered substance in a solvent and a dissolving step of dissolving a coating substance in a dispersion containing the exfoliated layered substance that has been disintegrated.
