description Provided are a cured product containing a single-layer graphene, a single-layer graphene, a preparation method therefor, and an article containing a single-layer graphene. The method for preparing the cured product containing a single-layer graphene includes (a) mixing graphite with a curable material and optionally a first solvent, and curing and molding same to obtain molded granules; (b) heating a system formed by the molded granules and optionally a second solvent, then introducing a gas for pressurization, and then releasing the pressure to obtain expanded granules; and (c) repeating step (a) and (b) several times, with the graphite and the curable material in step (a) replaced with the expanded granules, to obtain a cured product containing a single-layer graphene. The cured product containing a single-layer graphene is carbonized and separated to obtain a single-layer graphene. The article containing a single-layer graphene contains the cured product or the single-layer graphene.
