The most effective strategies to control biofouling release toxic and persistent agents into the aquatic environment causing environmental concerns leading implementation of more strict international legislation. This work presents recent progress on an innovative eco-friendly antifouling approach based isocyanate-functionalized Econea biocide allowing its chemical fixation in polymeric frameworks, namely, a foul-release marine coating. potential generated nonbiocide coatings for both...
Micro-texturing has been studied for many decades as a passive antifouling technology. However, most studies have experimental in nature and lack an informed basis the selection of micro-texture architecture. The herein reported preliminary numerical explored micro-textured superhydrophobic superhydrophilic surfaces mitigating biofouling related effects, such Microbial Induced Corrosion (MIC). Surface wettability manipulation is key mitigation strategy these issues. A computational model was...
Recent research efforts to mitigate the burden of biofouling in marine environments have focused on development environmentally friendly coatings that can provide long-lasting protective effects. In this study, antifouling performance novel polyurethane (PU)-based containing cyclam-based Fe(III) complexes against Cobetia marina biofilm formation was investigated. Biofilm assays were performed over 42 days under controlled hydrodynamic conditions mimicked environments. Colony-forming units...
The addition of biocides to marine coatings has been the most used solution avoid biofouling, however they are persistent, bioaccumulative, and toxic (PBT) ecosystems. development natural products or Nature-inspired synthetic compounds replace these harmfull pursued as one promising antifouling (AF) alternatives. Following a bioprospection strategy, we have previously reported AF activity gallic acid persulfate (1) against settlement Mytilus galloprovincialis larvae (EC50 = 18 µM LC50/EC50...
Marine biofouling represents a global economic and ecological challenge few eco-friendly antifouling agents are available. The aim of this work was to establish the proof concept that recently synthesized nature-inspired compound (gallic acid persulfate, GAP) can act as an effective antifoulant when immobilized in coatings through non-release strategy, promoting long-lasting effect. synthesis GAP optimized provide quantitative yields. water solubility assessed, showing values higher than...
Abstract Marine biofouling pollution is a process that impacts ecosystems and the global economy. On other hand, traditional antifouling (AF) marine coatings release persistent toxic biocides accumulate in sediments aquatic organisms. To understand putative impact on of recently described patented AF xanthones (xanthones 1 2), able to inhibit mussel settlement without acting as biocides, several silico environmental fate predictions (bioaccumulation, biodegradation, soil absorption) were...
Biofilms formed on submerged marine surfaces play a critical role in the fouling process, causing increased fuel consumption, corrosion, and high maintenance costs. Thus, biofouling is major issue motivates development of antifouling coatings. In this study, performance two commercial coatings, foul-release silicone-based paint (SilRef) an epoxy resin (EpoRef), was evaluated regarding their abilities to prevent biofilm formation by Cyanobium sp. Pseudoalteromonas tunicata (common...
The accumulation of marine biofouling on ship hulls causes material damage, the spread invasive species, and, indirectly, an increase in full consumption and subsequent pollutant gas emissions. Most efficient antifouling (AF) strategies rely conventional release persistent, bioaccumulative, toxic biocides incorporated coatings. A simple oxygenated xanthone, 3,4-dihydroxyxanthone (1), was previously reported as a promising AF agent toward settlement Mytilus galloprovincialis larvae, with...
The development of harmless substances to replace biocide-based coatings used prevent or manage marine biofouling and its unwanted consequences is urgent. formation biofilms on submerged surfaces one the first steps in process, which facilitates further settlement macrofoulers. Anti-biofilm properties a synthetic polyphenolic compound, with previously described anti-settlement activity against macrofoulers, were explored this work. In solution new compound was able biofilm reduce pre-formed...
Fibrous materials are often used in the manufacturing of fire protection devices such as curtains. Their optimization and improved performance is still a topic interest. The present work aims to develop test new combination fibers arranged various 2D 3D patterns with coatings. For this purpose, basalt were added into glass fiber fabric, wires shape memory material (SMM) inserted fabric create air pockets induced by temperature. In curtains, base structure basket pattern, all combinations...
Bio-contamination of water through biofouling, which involves the natural colonization submerged surfaces by waterborne organisms, is a global socio-economic concern, allied to premature materials bio-corrosion and high human health risks. Most effective strategies release toxic persistent disinfectant compounds into aquatic medium, causing environmental problems leading more stringent legislation regarding their use. To minimize these side effects, newly non-biocide-release coating strategy...
