“…Hydrolyzable polymers are traditionally used for the development of biocide-based erodible coatings with a self-polishing (SP) effect [ 14 ]. New strategies recently emerged in the field, which combine the advantages of biocide-free SP/FR in hybrid systems, incorporating hydrolyzable trialkylsilyl or bis(trimethylsiloxy)methylsilyl methacrylate-based polymers into a polymer matrix, either as an additive [ 40 , 41 ] or as a structural component [ 42 , 43 , 44 ]. When the polymer hydrolyzes, the surface becomes more hydrophilic and responsive to the external environment.…”

Amphiphilic Polyphosphonate Copolymers as New Additives for PDMS-Based Antifouling Coatings

Poly(ethyl ethylene phosphonate)-based methacrylic copolymers containing polysiloxane methacrylate (SiMA) co-units are proposed as surface-active additives as alternative solutions to the more investigated polyzwitterionic and polyethylene glycol counterparts for the fabrication of novel PDMS-based coatings for marine antifouling applications. In particular, the same hydrophobic SiMA macromonomer was copolymerized with a methacrylate carrying a poly(ethyl ethylene phosphonate) (PEtEPMA), a phosphorylcholine (MPC), and a poly(ethylene glycol) (PEGMA) side chain to obtain non-water soluble copolymers with similar mole content of the different hydrophilic units. The hydrolysis of poly(ethyl ethylene phosphonate)-based polymers was also studied in conditions similar to those of the marine environment to investigate their potential as erodible films. Copolymers of the three classes were blended into a condensation cure PDMS matrix in two different loadings (10 and 20 wt%) to prepare the top-coat of three-layer films to be subjected to wettability analysis and bioassays with marine model organisms. Water contact angle measurements showed that all of the films underwent surface reconstruction upon prolonged immersion in water, becoming much more hydrophilic. Interestingly, the extent of surface modification appeared to be affected by the type of hydrophilic units, showing a tendency to increase according to the order PEGMA < MPC < PEtEPMA. Biological tests showed that Ficopomatus enigmaticus release was maximized on the most hydrophilic film containing 10 wt% of the PEtEP-based copolymer. Moreover, coatings with a 10 wt% loading of the copolymer performed better than those containing 20 wt% for the removal of both Ficopomatus and Navicula, independent from the copolymer nature.

“…Degradable silicone is expected to have surface renewal to FRCs and thus improve the static antifouling property. Bressy et al prepared a new silicone coating that combined the silicone elastomers with a hydrolyzable polyester by a condensation reaction between bis-silanol PDMS and bis(trialkoxysilane)-terminated polyester macro-cross-linkers . Poly(ε-caprolactone) (PCL), poly( d , l -lactide- co -glycolide) (PLGA), and poly(ε-caprolactone)- b -PDMS- b -poly(ε-caprolactone) (PCL-PDMS-PCL) were used as hydrolyzable components.…”

Silicone-Based Fouling-Release Coatings for Marine Antifouling

Marine biofouling profoundly influences marine industries and activities. It slows the speed and increases the fuel consumption of ships, corrodes offshore platforms, and blocks seawater pipelines. The most effective and economical antifouling approach uses coatings. Fouling-release coatings (FRCs) with low surface free energy and high elasticity weakly adhere to marine organisms, so they can be readily removed by the water shear force. FRCs have attracted increasing interest because they are biocide-free and hence ecofriendly. However, traditional silicone-based FRCs have weak adhesion to substrates, low mechanical strength, and low fouling resistance, limiting their applications. In recent years, many attempts have been made to improve their mechanical properties and fouling resistance. This review deals with the progress in the construction of high-performance silicone-based fouling-release surfaces.

“From the nature, for the nature” is an instructive strategy to develop environment-friendly antifouling coatings. In this work, bio-sourced poly(lactic acid)-based polyurethane with hydrolyzable triisopropylsilyl acrylate (TSA) side groups has been prepared via thiol–ene reaction and polyaddition. Such a polymer exhibits high adhesion strength (∼2.0 MPa) and a controlled degradation rate tuned by varying its soft segment and TSA content. An environment-friendly coating is prepared with the polymer and an eco-friendly antifoulant (butenolide) derived from marine bacteria. Our study shows that butenolide can be released from the coating in continuous manner with a controlled rate as the polymer degrades in seawater. Digital holographic microscopy tracking analysis demonstrates that the coating can effectively inhibit the adhesion of marine bacteria Pseudomonas sp. Marine field test shows that such coating has excellent antifouling ability for more than 3 months.
