Since Novoselov et al. successfully exfoliated graphene from graphite in 2004 [1], applied research on graphene has become popular in many areas, including smart polymeric coatings. Industrial coatings, such as marine and automotive types, are composite materials that are reinforced with particulate fillers for imparting toughness, durability, colour, anti-corrosion protection, and other functions. The efficacy of a pigment depends on its physico-chemical nature and nano- sized fillers have previously been shown to require significantly less pigment to deliver the same performance as ?m-sized fillers [2]. Various nano-materials, such as graphene, ceramics and silver, are seeing increased usage in marine paint ...
