Title: PRE-TREATMENT COATING COMPOSITION AND A METHOD FOR PRODUCING THE SAME
Abstract:
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.
