Title
(EN) METHOD OF FORMING GRAPHENE/METAL-OXIDE HYBRID REINFORCED COMPOSITES AND PRODUCT THEREOF
(FR) PROCÉDÉ DE FORMATION DE COMPOSITES RENFORCÉS HYBRIDES GRAPHÈNE/OXYDE MÉTALLIQUE ET PRODUIT À BASE DE CEUX-CI
Abstract
(EN)
A graphene/metal-oxide hybrid reinforced composite and a method for a graphene/metal-oxide hybrid reinforced composite. The method includes freeze drying a slurry comprising graphene oxide and flakes to form a flake-graphene oxide foam. The graphene/metal-oxide hybrid reinforced composite comprises graphene, metal, and metal oxide nanoparticles. The metal is arranged in parallel lamellar structure to form metal layers in the composite. The metal oxide nanoparticles are present at the interfaces between the metal layers and the graphene.

L'invention concerne un composite renforcé hybride graphène/oxyde métallique et un procédé associé. Le procédé consiste à lyophiliser une suspension comprenant de l'oxyde de graphène et des paillettes pour former une mousse à base de paillettes-oxyde de graphène. Le composite renforcé hybride graphène/oxyde métallique comprend du graphène, du métal et des nanoparticules d'oxyde métallique. Le métal est agencé sous la forme d'une structure lamellaire parallèle pour former des couches de métal dans le composite. Les nanoparticules d'oxyde métallique sont présentes à l'interface entre les couches métalliques et le graphène.
