Marine fouling organisms attachment can bring serious damage to ships and marine facilities. Thus, we modified the hydrophobic fluorocarbon resin coating (PEVE) which was widely used in marine hulls. In this study, graphene/TiO2 nanocomposite photocatalysts have been taken as the raw material of the modification to prepare the composite coatings with anti-fouling performance through a sample method. The results of our experiment demonstrate that when the mass ratio of rGO to TiO2 is 1:100, the composite coating exhibits the best antibacterial property. This coating could kill the vast majority of the bacteria which attached to its surface after one hour of exposure to ultraviolet light, and this sterilization performance is much higher than pure PEVE and TiO2/PEVE coatings. In this composite system, graphene plays an important role in enhancing the coatings performance. For one thing, the heterojunction formed by graphene and TiO2 can effectively increase the hydroxyl radical yields of TiO2. For another, the conjugated structure of graphene can effectively reduce the phenomenon of hydrophobicity reduction which is caused by the addition of TiO2 and then decrease the risk of hull corrosion availably.
