“…Therefore, scientists have chemically modified titanium dioxide so that it can be activated by visible light (in the blue region of the spectrum), which will improve its performance under poor light conditions. In addition to laboratory tests, researchers are conducting long-term field experiments on a large number of commercial coating formulations that have adopted photocatalytic technology [146,147].…”

“…While the ship is sailing, the UV light intensity received at the bottom is poor, which limits its large-scale commercial use. To further strengthen the advantages of photocatalytic coatings, Trávníčková et al [146] investigated eight complex surfaces with different contents of TiO 2 , alkoxysiloxane, and a hydrophobic agent and compared them to select the surface components that can inhibit the growth of photooxy filamentous Kerry algae. The results showed that photocatalysis combined with superhydrophobic surfaces during the early attachment of biological stains could effectively prevent a large number of fouling spores from gathering and forming a biofilm.…”

The shipping industry is vital to global trade. Unfortunately, this industry is negatively impacted on a large scale by biofouling, a process whereby unwanted organisms accumulate on submerged surfaces, massively affecting traveling speed and fuel consumption. Fortunately, antifouling coatings have been developed to combat this problem. This review summarizes the process of biofouling and briefly discusses the history of antifouling coating development. Moreover, eight major antifouling coatings are reviewed, including bionic microstructure, self-polishing, fouling and desorption, zwitterionic polymer, self-assembled thin-layer, liquid-smooth surface, conductive, and photocatalytic antifouling coatings. The technical principles, innovation, and advancement of each coating are expounded, and the relevant research progress is discussed. Finally, the remaining issues and challenges in antifouling coatings are discussed, along with their prospects.

“…In recent years, photocatalytic materials have shown great potential for environmental protection and energy utilization because of their environmental friendliness and high efficiency [ 12 , 13 ]. Meanwhile, photocatalytic materials have been proved to have superior anti-bacterial properties [ 14 , 15 , 16 ]. When photocatalytic materials are irradiated by incident light with energy greater than their forbidden bandwidth, the valence band electrons are excited to the conduction band, generating electron–hole pairs and undergoing redox reactions.…”

Fluorescent antifouling and photocatalytic antifouling technologies have shown potential in the field of marine antifouling. SLAP@g-C3N4/PDMS (SLAP@CN/PDMS) composite antifouling coatings were designed and prepared using g-C3N4, sky-blue long afterglow phosphor (SLAP), and polydimethylsiloxane (PDMS). The fluorescence emitted by SLAP under dark conditions was used to excite g-C3N4 for fluorescent photocatalysis and to prolong the photocatalytic activity of g-C3N4. Key data were collected by testing and characterization and are presented in this work. The results showed that g-C3N4 was successfully coated on the SLAP surface and formed a heterogeneous structure. After the composite powder was added to the PDMS coating, the coating maintained low surface energy but enhanced the surface roughness of the coating. The experimental results of degraded Rhodamine B (RhB) showed that SLAP prolonged the g-C3N4 photocatalytic activity time. The anti-marine bacterial adhesion performance of the coating was investigated by bacterial adhesion experiments. The results showed that SLAP@CN could effectively improve the anti-bacterial adhesion performance of PDMS coating, in which the anti-bacterial adhesion performance of SLAP@CN-2.5/PDMS was improved by nearly 19 times. This antifouling coating introduces fluorescent antifouling, photocatalytic antifouling, and fluorescence-driven photocatalytic antifouling based on the low surface energy antifouling of silicones and achieves “all-weather” fluorescent photocatalytic antifouling.
