Title
(EN) GRAPHENE ANTI-CORROSION COATING
(FR) REVÊTEMENT ANTI-CORROSION À BASE DE GRAPHÈNE
(ZH) 一种石墨烯防腐涂料
Abstract
(EN)
A graphene anti-corrosion coating, comprising an epoxy resin and graphene subjected to surface modification. The addition amount of the graphene is 0.01-0.2 wt% of the total mass of the coating solid. By performing surface modification on the graphene, dispersity of the graphene in the coating is improved, and the compactness of the coating is enhanced.
(FR)
La présente invention concerne un revêtement anti-corrosion à base de graphène, comprenant une résine époxyde et du graphène soumis à une modification de surface. La quantité d'addition du graphène est de 0,01 à 0,2 % en poids de la masse totale du solide de revêtement. En effectuant une modification de surface sur le graphène, la dispersité du graphène dans le revêtement est améliorée, et la compacité du revêtement est améliorée.
