Antifouling coatings play a vital role in the marine industry for the prevention and/or control of marine biofouling attach and growth on submerged surfaces. This undesired bio-attach has been associated with serious economic and environmental penalties on both stationary and non-stationary (mobile) marine systems, from shipping, fisheries, aquaculture (e.g., cages) and other offshore activities, for instance, oil/wind-turbine-sea-platforms, desalination units, pipelines, water valves, filters and sensors. It can promote substrate deterioration, systems clogging, drag friction and fluids contamination, follow-on costly maintenance and retrofitting consequences.
Along the history of protective marine coatings, several antifouling strategies have been exploited. The most revolutionary coatings generation was marked by the appearance of the tributyltin (TBT) releasing based antifouling coatings, around the 1960s, owing to their high efficacy and broad spectrum toxic action, able to provide huge operational savings. But soon this solution was abandoned due to its harmful effects on the marine ecosystem, being totally banned in 2008. Since then, efforts have been done to replace this toxic agent and/or derivatives. Most conventional antifouling strategies (e.g., soluble polymeric matrices, controlled depletion polymer coatings (CDPs), self-polishing tin-free copolymer coatings (TF-SPC)) are however still acting by controlled-releasing mechanisms of toxic agents or booster biocides. Despite being considered less toxic to the aquatic environment, the global environmental concern has been leading to severe restrictions on their use. Alternative strategies, mostly inspired by the observation of natural chemical-physical antifouling defense mechanisms, have been emerging, from foul-releasing systems, biopassive polymeric coating, microtopography modified polymers, among others. Even so, these strategies still do not accomplish an effective effect comparable to the TBT generation or involve costly implementations.
Efforts are required to provide new strategies able to offer more efficient and sustainable environmental-friendly antifouling solutions, as well as to overcome major challenges, such as the complexity of the biofouling process and the global warming, able to inflict serious impacts in the marine ecosystem.
This Special Issue of Coatings on "Novel Marine Antifouling Coatings" is intended to cover the most recent and promising advances in marine antifouling coatings.
The main topics that this Special issue of Coatings will encompass are:
- Foul-releasing coatings;
- Antifouling self-healing coatings;
- Non-releasing biocidal coatings;
- Biopassive based polymeric coatings (zwitterionic, self-assembled monolayers approaches);
- Bioinspired coatings (incorporating natural and/or new synthesized biomimetic based agents, microtopographically modified coatings);
- Hybrid and/or multifunctional coatings (amphiphilic/stimuli-responsive systems).

Provisional title: Recent Advances in Mussel-Inspired Synthetic Polymers as Marine Antifouling Coatings
Author: Ioannis Manolakis
Synthetic oligomers and polymers inspired by the multifunctional tethering system (byssus) of the common mussel (genus Mytilus) have emerged since the 1980s as a very active research domain within the wider bioinspired & biomimetic materials arena. The unique multifunctionality of the mussel byssus with strong underwater adhesion, robust mechanical properties and self-healing capacity has been linked to a large extent to the presence of the unusual α-aminoacid derivative L-DOPA (L-3,4-dihydroxyphenylalanine) as a building block of the mussel byssus proteins. This paper provides a short overview of biofouling in the marine environment, discussing the different marine biofouling species & mechanisms, natural defenses against marine biofouling, as well as biomimicry as a concept investigated and applied in the marine antifouling context. A detailed discussion of the literature on the Mytilus mussel family follows, covering elements of their biology, biochemistry and the specific measures adopted by these mussels to utilise their L-DOPA-rich protein sequences (and specifically the ortho-bisphenol (catechol) moiety) in their benefit. Then a comprehensive account is given of the key catechol chemistries (both covalent and non-covalent/intermolecular) relevant to adhesion, cohesion and self-healing, as well as of some of the most characteristic mussel protein synthetic mimics reported over the past 30 years and the related polymer functionalisation strategies with L-DOPA/catechol. Lastly, we review some of the most recent advances in such mussel-inspired synthetic oligomers and polymers, claimed as specifically aimed or intended for use in marine antifouling coatings and/or tested against marine biofouling species.
