GRAPHENE AND OTHER 2D MATERIALS AS LAYERED "SHELLS" SUPPORTED ON "CORE" NANOPARTICLE CARRIERS

Nº publicación: US2019334179A1 31/10/2019

Solicitante:

BRETON SPA [IT]

KR_20190104549_A

Resumen de: US2019334179A1

The invention refers to hierarchical nanocomposites including layered materials supported on suitable carriers. In a preferential aspect of the invention, the layered materials consist of graphene and related materials. In a preferential aspect of the invention, the carrier consists of nanoparticles characterized by a Mohs hardness higher than that of the layered materials included in the hierarchical nanocomposite. These materials, which consist of “core” nanoparticles (the carrier) wrapped by layered systems (the “shell”) such as graphene, graphene oxide and other graphene and related materials (GRMs), are suitable precursors to obtain inks with water. The hierarchical “core-shell” nanocomposites are obtained by a preparation procedure including at least one “in situ” mechanical exfoliation step of the layered materials. The mechanical exfoliation step is carried out owing to a reciprocal friction process between the components of the precursor mixture, that incorporates both the precursors of the layered materials and those of the supporting “core” carriers. The materials are suitable to prepare inks where “core” nanoparticles act as carriers for the single/few-layered supported graphene or GRM.
