1. A method of providing an anti-microbial coating on an object, comprising the steps of:
pre-treating the object in a first oxygen plasma to graft oxygen-based functional groups on the surface of the object by plasma enhanced chemical vapour deposition;
coating the pre-treated object with a suspension of particulate graphene oxide to provide a graphene oxide coating on the object;
treating the object in a hydrocarbon plasma to deposit an amorphous hydrocarbon film on the graphene oxide coating by plasma enhanced chemical vapour deposition; and
treating the object in a second oxygen plasma configured to etch and flatten the coatings on the surface of the object.
