Graphene oxide is a carbon-based material similar to carbon nanotubes and fullerenes. This nanosized black powder has been shown to improve corrosion resistance in protective coatings. Being a nanopowder, graphene oxide has a very high surface area and is extremely difficult to wet and disperse in coating systems. Industrial hygiene issues have been a deterrent to the broader use of graphene oxide in powder coatings. This presentation will provide information on composite powders based on combinations of graphene oxide with polyolefin waxes. The resulting graphene oxide composite powders are easier to use and safer to handle in laboratories and manufacturing facilities. Corrosion resistance data will be presented to demonstrate the benefit of graphene oxide modification in coatings applied over both bare and FePO4 pretreated cold rolled steel substrates. A second-generation graphene composite powder suitable for both water- and solvent-based coatings will also be presented.
