Abstract

See full text

Provided is a production method which can attain exfoliating treatment of graphite and a process of grafting a polymer onto exfoliated graphite simultaneously and thus makes it possible to easily obtain an exfoliated graphite-polymer composite material in a short time. A method for producing an exfoliated graphite-polymer composite material includes a step of mixing graphite or primary exfoliated graphite, a depolymerizable monomer of which the polymer is decomposed by heating to generate radicals and also to form a monomer or an oligomer, or the polymer A of the monomer, or a polymer B which forms radicals at a temperature close to its decomposition temperature to obtain a mixture; and a heating step of putting the mixture in a non-open container to heat the mixture to a first temperature range from the ceiling temperature or higher to the onset decomposition temperature or lower, or to a temperature higher than the first temperature range.
