摘要: Abstract 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 hulls. In this study, graphene/TiO2 nanocomposite photocatalysts have been taken as raw material of modification prepare composite coatings with anti-fouling performance through a sample method. The results our experiment demonstrate that when mass ratio rGO TiO2 is 1:100, exhibits best antibacterial property. This could kill vast majority bacteria attached its surface after one hour exposure ultraviolet light, sterilization much higher than pure PEVE TiO2/PEVE coatings. system, graphene plays an important role enhancing performance. For thing, heterojunction formed by effectively increase hydroxyl radical yields TiO2. another, conjugated structure reduce phenomenon hydrophobicity reduction caused addition then decrease risk hull corrosion availably.
