Reduced_x000D_
graphene oxide (rGO) is a great candidate in this arena as it can be used in water lubricated coatings, offering_x000D_
an environmentally safe replacement to oil lubrications in oil tankers and pipelines. Significant efforts focused_x000D_
on developing methods to produce rGO thin-films through thermal, chemical or electrical treatments. However,_x000D_
the most common protocols for reducing graphene oxide (GO) to rGO rely on using toxic solvents, causing_x000D_
serious safety and environmental concerns. The growth of rGO directly on stainless steel for implant_x000D_
applications has not been assessed. We recently developed a simple process for growing multilayer rGO films_x000D_
on stainless steel (SS316L) surfaces using solution-phase molecular precursors of coronene. Coronene is_x000D_
basically a small flake of graphene which can undergo dimerization by subsequent annealing. Our process_x000D_
consists of drop casting a solution of coronene on SS316L, followed by thermal annealing under air and_x000D_
subsequent cooling. Th rGO coating enhances the mechanical properties of SS316L for various applications._x000D_
We also improved a number of factors such as good film uniformity and thickness control, minimization of_x000D_
solution consumption, large area deposition capability, and cost effectiveness. Our approach elucidates the_x000D_
structure/function relationship in the rGO films, targeting corrosion-resistance properties that lead to durability,_x000D_
reliability, survivability and maintainability of rGO thin-films. The diverse applicability of our method makes it_x000D_
promising and warrants market assessment. Such anticorrosive coatings are expected to have a significant_x000D_
impact on the Canadian industry including manufacturing, automotive and submarine technologies., program purpose french : A major challenge in modern materials engineering is to make cost effective anticorrosive coatings. Reduced_x000D_
