1. A method for producing a composite material comprising an exfoliated layered substance and a coating substance coating a surface of the exfoliated layered substance, the method comprising:
disintegrating secondary particles of an exfoliated layered substance in a solution containing a coating substance,
wherein the exfoliated layered substance is derived from natural graphite,
wherein the coating substance is glycidyl ether of bisphenol or a polyvinyl compound, and
wherein the disintegration of the secondary particles of the exfoliated layered substance is performed using a dispersion machine selected from the group consisting of a high-speed rotary shearing type stirring machine, a stirred media mill, a container-driven mill, a colloid mill, a high-pressure emulsifying machine, and an ultrasonic emulsifying machine.
