“…Below a ratio of 0.1, droplet presents isotropic-like behavior which is consistent with Damle et al's conclusions. [105,106,109] Wolansky and Marmur had come to a similar conclusion for size of topography features, saying that the anisotropy of the wetting properties of topographies organized symmetrically translationally could only exist for wide enough features compared to the size of the droplet. [111] However, Long et al analyzed different studies on the anisotropy of wetting properties of topographically patterned surfaces.…”

“…[109] Wang et al modelized the behavior of a water droplet on a patterned surface depending on the ratio of the width of a period of stripes and the ratio of the width of a hydrophilic stripe to the width of a period of stripes. [106] The modelling showed that for a ratio of the width of a period of stripes higher than 0.1, anisotropic wetting behavior starts to appear. Below a ratio of 0.1, droplet presents isotropic-like behavior which is consistent with Damle et al's conclusions.…”

“…[48,82,100,101] Surfaces with topographies or chemistries organized symmetrically translationally, for example organized in arrayed pits or regularly spaced channels, showed increased contact angle, but also anisotropy of the wetting properties, such as contact angle, contact angle hysteresis, free energy barrier or advancing and receding contact angle. [92,[102][103][104][105][106][107][108][109][110] This anisotropy of the wetting properties could disappear for dimensions below a certain size. [106,109] Damle and Rykaczewski investigated the wetting properties of a chemically heterogeneous surface, with two different chemistries organized in stripes of a certain width.…”

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...

Droplet impingement and anisotropic wetting on chemically heterogeneous stripe-patterned surfaces is simulated by means of many-body dissipative particle dynamics (MDPD). The ratio of the stripe width and initial droplet diameter, defined as β, ranges from 0.5 to 1.0 so that the wetting process is in the Beyond-Cassie-Baxter regime and is highly anisotropic. At zero Weber number (that is, without considering droplet inertia) and with superhydrophobic stripes, β is the only factor affecting the droplet perpendicular contact angle and aspect ratio. For inertial droplets, β and the Weber number are found to have an effect on the eventual droplet morphology on multi-striped surfaces. These morphologies include elongated shape, split-off, and "butterfly" shape. A correlation for critical split-off conditions has been determined. An energy analysis of droplet impingement shows that the normalized surface energy of the droplet is independent of the Weber number if the droplet is elongated or butterfly-shaped.
