Silicone-Based Lubricant-Infused Slippery Coating Covalently Bound to Aluminum Substrates for Underwater Applications

Popis výsledku v původním jazyce

Wetting of solid surfaces is crucial for biological andindustrialprocesses but is also associated with several harmful phenomena suchas biofouling and corrosion that limit the effectiveness of varioustechnologies in aquatic environments. Despite extensive research,these challenges remain critical today. Recently, we have developeda facile UV-grafting technique to covalently attach silicone-basedcoatings to solid substrates. In this study, the grafting processwas evaluated as a function of UV exposure time on aluminum substrates.While short-time exposure to UV light results in the formation oflubricant-infused slippery surfaces (LISS), a flat, nonporous variantof slippery liquid-infused porous surfaces, longer exposure leadsto the formation of semi-rigid cross-linked polydimethylsiloxane (PDMS)coatings, both covalently bound to the substrate. These coatings wereexposed to aquatic media to evaluate their resistance to corrosionand biofouling. While the UV-grafted cross-linked PDMS coating effectivelyinhibits aluminum corrosion in aquatic environments and allows organismsto grow on the surface, the LISS coating demonstrates improved corrosionresistance but inhibits biofilm adhesion. The synergy between facileand low-cost fabrication, rapid binding kinetics, eco-friendliness,and nontoxicity of the applied materials to aquatic life combinedwith excellent wetting-repellent characteristics make this technologyapplicable for implementation in aquatic environments.
