A first object of the present invention is to provide a surface-modified inorganic nitride having excellent dispersibility. Furthermore, a second object of the present invention is to provide a composition, a thermally conductive material, and a device with a thermally conductive layer which contain the surface-modified inorganic nitride.
The surface-modified inorganic nitride of the present invention includes an inorganic nitride, and a specific compound adsorbed onto a surface of the inorganic nitride, and
the specific compound has a functional group selected from the group consisting of a boronic acid group, an aldehyde group, an isocyanate group, an isothiocyanate group, a cyanate group, an acyl azide group, a succinimide group, a sulfonyl chloride group, a carboxylic acid chloride group, an onium group, a carbonate group, an aryl halide group, a carbodiimide group, an acid anhydride group, a carboxylic acid group, a phosphonic acid group, a phosphinic acid group, a phosphoric acid group, a phosphoric acid ester group, a sulfonic acid group, a halogenated alkyl group, a nitrile group, a nitro group, an ester group, a carbonyl group, an imidoester group, an alkoxysilyl group, an acrylic group, a methacrylic group, an oxetanyl group, a vinyl group, an alkynyl group, a maleimide group, a thiol group, a hydroxyl group, a halogen atom, and an amino group, and has a fused-ring structure containing two or more rings selected from the group consisting of an aromatic hydrocarbon ring and an aromatic heterocyclic ring.
