“…Besides silver, alumina and silica nanoparticles have also been used in conjunction with GO, having both demonstrated excellent antimicrobial properties against a wide range of organisms [ 68 , 69 ]. In turn, the functionalization of GO with polyaniline/p-phenylenediamine conferred anticorrosion and AF properties to commercialized epoxy coatings [ 72 ]. Likewise, the modifications of GO materials with compounds such as cuprous oxide, acrylic acid, or boehmite nanorods, produced AF coatings with high self-cleaning performance and durability in marine environments (up to 6 months) ( Figure 7 ) [ 70 , 71 , 73 ].…”

Although carbon materials are widely used in surface engineering, particularly graphene (GP) and carbon nanotubes (CNTs), the application of these nanocomposites for the development of antibiofilm marine surfaces is still poorly documented. The aim of this study was, thus, to gather and discuss the relevant literature concerning the antifouling performance of carbon-based coatings against marine micro- and macrofoulers. For this purpose, a PRISMA-oriented systematic review was conducted based on predefined criteria, which resulted in the selection of thirty studies for a qualitative synthesis. In addition, the retrieved publications were subjected to a quality assessment process based on an adapted Methodological Index for Non-Randomized Studies (MINORS) scale. In general, this review demonstrated the promising antifouling performance of these carbon nanomaterials in marine environments. Further, results from the revised studies suggested that functionalized GP- and CNTs-based marine coatings exhibited improved antifouling performance compared to these materials in pristine forms. Thanks to their high self-cleaning and enhanced antimicrobial properties, as well as durability, these functionalized composites showed outstanding results in protecting submerged surfaces from the settlement of fouling organisms in marine settings. Overall, these findings can pave the way for the development of new carbon-engineered surfaces capable of preventing marine biofouling.

“…They show excellent macroscopic antifouling properties in the experiments performed at typical marine conditions. [104,105] Scheme of synthesis process for the epoxy coatings reinforced with polyaniline (PANI)/p-phenylenediamine-functionalized GO (PGO) and the PANI-PGO nanocomposites is illustrated in Figure 15a. Selected PANI-PGO composites of different mass ratios were employed, while the sample with 1:1 mass ratio is shown in the figure.…”

Sea vessels and artificial sea‐based structures are severely affected by biofouling, i.e., the formation of deposits of living and dead marine organisms that belong to different species and range in size from unicellular bacteria to multicellular seaweed and mussels. This is a significant engineering problem since they essentially alter the geometry of the hull, increasing friction and reducing the speed of vessels, thus increasing the cost and environmental footprint of transportation. Given the scale of global transportation reaches several billion tons per year, the socioeconomic consequences of the reduction in transit speed and increased consumption of fuel continue to drive researchers and engineers to develop strategies to combat the processes of marine biofouling. Many types of antifouling paints, coatings, and materials that have been designed and tested, and in some instances used commercially, suffer from shortcomings ranging from environmental toxicity to limited efficiency and durability. In this review article, a brief overview of the traditional antifouling materials is presented and recent achievements in the design of advanced antifouling materials based on such nanomaterials as graphene, nanotubes, nanoparticles, and more complex nanostructures are discussed. These materials exhibit excellent antifouling properties and candrive a breakthrough in how marine biofouling is tackled.

“…Extremely high levels of oxygen and large amounts of algae and bacteria are indicators of a hazardous marine environment. Seawater acts as a powerful corrosive medium; hence mild steel will certainly face significant corrosion in the harsh marine environment. − Because of the presence of chloride ions or other aggressive species in seawater, the passivity of the steel may be affected by the breakdown of the passive layer. It produces corrosion on the metal surfaces of the infrastructure, which results in a number of problems, including safety risks and significant financial losses due to the time and money needed to repair and replace the equipment. , Corrosion protection technology for mild steel in a marine environment has thus emerged as a popular study area.…”

With the help of (3-trimethoxysilylpropyl) diethylenetriamine (TMSPETA), hafnium(IV) oxide (HfO2), an inorganic nanofiller, was modified. The resulting TMSPETA/HfO2 was then encased in graphitic carbon nitride (GCN) and placed within a pure epoxy resin (EP). The protective behavior of mild steel coated with epoxy in the presence of various concentrations of GCN/TMSPETA-HfO2 was studied using electrochemical methods in seawater environment. It was found that the addition of 0.6 wt % of GCN/TMSPETA-HfO2 to the epoxy resin produced maximum resistance. Hence, the optimum concentration of 0.6 wt % was utilized for further investigation. The PHRR and THR values for the GCN/TMSPETA-HfO2 significantly decreased by 73% and 57%, respectively, as compared to pure EP, showing that the material is more flame retardant. The results of salt spray tests showed that the inclusion of GCN/TMSPETA-HfO2 in the epoxy matrix enhanced the corrosion protection performance and reduced water absorption. EIS measurements showed that the epoxy-GCN/TMSPETA-HfO2 had increased coating resistance of 6.42E9 Ω·cm2 even after 320 h of exposure to seawater. According to SECM investigations, the coated steel with EP-GCN/TMSPETA-HfO2 nanocomposite has the lowest ferrous ion dissipation (1.0 I/nA). FE-SEM/EDX investigation revealed that silanized GCN was enhanced in the degradation products, resulting in a durable inert nanolayered covering. The newly created EP-GCN/TMSPETA-HfO2 coating was incredibly water-resistant, with a WCA of 165°. The TMSPETA-HfO2 wrapped in GCN has demonstrated strong adhesion and hardness in the epoxy substrate as well as good mechanical properties. An increased adhesive strength (19.1 MPa) was achieved for mild steel coated with EP-GCN/TMSPETA-HfO2 prior to being immersed in seawater. As a result, the coating has greater adhesive strength and can hold up even after a prolonged immersion. In light of this, the EP-GCN/TMSPETA-HfO2 nanocomposite may be used as a coating component in the automotive industry.
