“…Similar observations were made previously for amphiphilic PEG block copolymers. [ 20,32,52 ] The good performance of amphiphilic zwitterionic polymers is in line with many results in literature showing high resistance against cell adhesion, [ 30 ] attachment of N. incertia , [ 29 ] and a good anti‐fouling performance against zoospores of U. linza .

Amphiphilic polymer coatings combining hydrophilic elements, in particular zwitterionic groups, and hydrophobic elements comprise a promising strategy to decrease biofouling. However, the influence of the content of the hydrophobic component in zwitterionic coatings on the interfacial molecular reorganization dynamics and the anti-fouling performance is not well understood. Therefore, coatings of amphiphilic copolymers of sulfobetaine methacrylate 3-[N-2'-(methacryloyloxy)ethyl-N,N-dimethyl]-ammonio propane-1-sulfonate (SPE) are prepared which contain increasing amounts of hydrophobic n-butyl methacrylate (BMA). Their fouling resistance is compared to that of their homopolymers PSPE and PBMA. The photo-crosslinked coatings form hydrogel films with a hydrophilic surface. Fouling by the proteins fibrinogen and lysozyme as well as by the diatom Navicula perminuta and the green algae Ulva linza is assessed in laboratory assays. While biofouling is strongly reduced by all zwitterionic coatings, the best fouling resistance is obtained for the amphiphilic copolymers. Also in preliminary field tests, the anti-fouling performance of the amphiphilic copolymer films is superior to that of both homopolymers. When the coatings are exposed to a marine environment, the reduced susceptibility to silt incorporation, in particular compared to the most hydrophilic polyzwitterion PSPE, likely contributes to the improved fouling resistance.

“…[213] It has also been suggested that incorporating of relatively small amount of zwitterions into polymer coatings could enhance fouling-release properties. [215,216] Recently, Knowles et al have chosen to investigate the antifouling behavior of coatings prepared from silica nanoparticles (SiNPs) of various sizes grafted with hydrophilic zwitterionic chemistries. The coatings demonstrated a high degree of nonspecific protein resistance: adsorption of bovine serum albumin and hydrophobin proteins were reduced by up to 91% and 94%, respectively.…”

the hulls could limit the undesirable effects but together increase the costs both in time and money. Consequently, biofouling is costing billions of dollars each year to naval industry. [8,9] When talking about colonization on marine sensors, Delauney et al. showed that biofouling affected the sensitivity and caused drift of measurements of the device over time. [10] Biofouling is also a big issue in the case of renewable marine energy devices. Biofouling on wave energy converters (WEC) leads to the decrease in efficiency of the devices by increasing drag and is also responsible of local biocorrosion. [11,12] The maintenance of such structure is risky and expensive, requiring period of good weather and calm sea state, among others. [13] Maintenance is all the more necessary during summer when fouling is the most intensive, due to higher seawater temperature, solar irradiation, and number of organisms. [13,14] In aquaculture, biofouling is also a major concern. Fitridge et al. reviewed all the effect of marine biofouling and its control in aquaculture. [15] Indeed, it can be responsible of cage deformation and structural fatigue, it will reduce the quality of water by limiting oxygen availability or increase the disease risk for fish species. Considering shellfish, biofouling can be responsible of mortality, shell erosion, competition for food and space, or disturbance in shell growth, for instance.In desalination plants, settlement, and accumulation of foulers onto the surface of the membranes or its pores lead to a deterioration of the filter. Salt rejection is negatively affected by the degradation of the membrane due to fouling. [16] Preventing fouling appears consequently a major concern for naval and marine industry, including sustainable domains like aquaculture, desalination plant, or the development of marine renewable energy devices.Protecting marine infrastructures has been the main matter of concern since the beginning of maritime transports. Tar, wax, arsenic, asphalt, or pitch are thought to be components used during antiquity for the first antifouling coatings. [3,5] Phoenicians and Carthaginians possibly used copper plates to protect their ships. [3,5] In the early 18th century, boats started to be made of steel. Zinc, nickel, and lead were chosen instead of copper plates to protect ships, because of corrosion matter. [3,17] From the late 18th century, heavy metal were more and more Marine biofouling is the unwanted accumulation of biological origin matters on submerged surfaces. Biofouling is a major economic burden on navy and commercial ships, as well as civil structures, piping systems, sensors, and power generating facilities. Due to the vast variety of marine organisms that colonize submerged surfaces, no surface has been found that is completely resistant to marine biofouling. The development of bioinspired and textured surfaces and their effects on marine biofouling are reviewed here. Different parameters such as mechanical properties, wettability, and surface topo graphy are shown to have...

“…After 75 days the samples were removed and tested for biofilm release in a variable-speed hydrodynamic flow-cell (Politis et al 2009). The fouled microscope slides were installed in the flow cell and fully turbulent seawater was passed along the surfaces as described in the literature (Ventura et al 2017;Benschop et al 2018). The water velocity was incrementally increased from zero to 4.1 m s À1 (1.5, 2.1, 2.6, 3.1, 3.6 and 4.1 m s À1 ), while remaining constant at each speed for 1 min.…”

New processing routes and materials for non-biocidal, antifouling (AF) coatings with an improved performance are currently much sought after for a range of marine applications. Here, the processing, physical properties and marine AF performance of a fluorinated coating based on a thermoplastic (non-crosslinked) fluorinated polymer are reported. It was found that the addition of lubricating oil and hydrodynamic drag reducing microstructures improved the AF properties substantially, i.e. the settlement of a marine biofilm, containing mixed microalgae including diatoms, was reduced to low levels. More importantly, the remaining fouling was removed from the coatings at low hydrodynamic shear rates and promising AF properties were obtained. Moreover, additional potential benefits were revealed originating from the thermoplastic nature of the coating material which might result in significant cost reductions.
