| Abstract |
| Since the use of tributyltin compounds in antifouling coatings was prohibited in 2003, the search for environmentally friendly alternatives has intensified. Because of their nonstick, environmental, and economic benefits, fouling-release nanocoatings have received a lot of attention. They use physical anti-adhesion terminology to deter any fouling attachment. Superhydrophobic bioinspired surfaces have micro/nanoroughness and low free energy characteristics, which can motivate dynamic antifouling surface fabrication. Polymer/graphene nanocomposite coatings have been designed to combat biofouling adhesion with ecological and ecofriendly effects, rather than biocidal solutions. Because of their improved interaction at the filler-polymer interface for nanocomposites, graphene-based nanofillers have been used as novel class of composite materials in fouling-prevention applications. Graphene hybrid metal oxide fillers can be used as functional coating nanofillers that would release fouling and confer surface robustness were facilely created by using a straightforward one-phase ultrasonication technique. Long-term durability and self-cleaning performance are among the advantages of developing effective, stable, and ecofriendly modeling alternatives. Water contact angle, surface free energy, and water contact angle were employed to examine the superhydrophobicity and micro/nanoroughness of the coatings. The antifouling effects of the coating systems were evaluated in the laboratory using specific microorganisms. Bioinspired polymeric/graphene nanocomposites can develop efficient and eco-friendly superhydrophobic and durable antifouling coatings. |
