Title (EN) PRE-TREATMENT COATING COMPOSITION AND A METHOD FOR PRODUCING THE SAME
(FR) COMPOSITION DE REVÊTEMENT PRÉTRAITEMENT ET PROCÉDÉ DE PRODUCTION ASSOCIÉ
Abstract: front page image
(EN)The invention relates to a method for producing a pre-treatment coating composition for a metal substrate, the method comprising the steps of: i. mining graphite ore from a graphite ore body; ii. subjecting the graphite ore to an electrolytic treatment to obtain an expanded graphitic material; iii. subjecting the expanded graphitic material to an exfoliation treatment to obtain single-layer graphene and few-layer graphene, and iv. functionalising the graphene with a coupling agent for coupling graphene to the metal substrate.
(FR)L'invention concerne un procédé de production d'une composition de revêtement prétraitement pour un substrat métallique, le procédé comprenant les étapes suivantes : i. extraction de minerai de graphite d'un corps de minerai de graphite; ii. soumission du minerai de graphite à un traitement électrolytique pour obtenir un matériau graphitique expansé; iii. soumission du matériau graphitique expansé à un traitement d'exfoliation pour obtenir du graphène monocouche et du graphène à quelques couches, et iv. fonctionnalisation du graphène avec un agent de couplage pour coupler le graphène au substrat métallique.
