Method for exfoliating carbonaceous materials containing graphite, assisted by a Diels-Alder reaction

摘要

The present invention relates to a process for exfoliating graphite in carbonaceous materials facilitated by a Diels-Alder reaction, and the applications of same, in particular for producing electronic or microelectronic components such as transparent conductive electrodes. The inventive method comprises a Diels-Alder reaction between a material containing graphite and an anthrone compound represented by formula (I), wherein X, R₁, R₂, R₃ and R₄ are as defined in the description, in an organic solvent, in the presence of a base, and subjected to sonication, ball-milling and/or high-shear mixing, at a temperature of between 15° C. and 65° C., to obtain the corresponding graphene Diels-Alder adduct.
