Abstract: Provided is a method for effectively modifying a surface of a h-BN particle including a (0001) plane, which is a base surface of h-BN, with a variety of materials.
A method for producing a surface-coated hexagonal boron nitride particle of one embodiment includes mixing a hexagonal boron nitride particle (a), a coupling agent (b), and a catalyst (c) having a polar group and an aromatic ring in a solvent to form a layer containing a condensate of the coupling agent on at least a portion of a surface of the hexagonal boron nitride particle.
