“…28 LISs promote excellent repellency to a broad range of liquids, 28,29 in which such slippery surface can be translated as an advance at minimizing adhesion of bacteria cells and thus preventing biofouling. [30][31][32][33][34] LISs are fabricated by infusing a lubricant liquid into rough textured or porous film substrates to obtain smooth slippery surfaces. 35 The textured or porous substrates are comprised of micro-or nanostructures such as micropillars and wells which aim to hold the lubricant sturdily within the solid textures via capillary and intermolecular forces.…”

Microbial biofilm build-up in water distribution systems can pose a risk to human health and pipe material integrity. The impact is more devastating in space stations and to astronauts due to the isolation from necessary replacement parts and medical resources. As a result, there is a need for coatings to be implemented onto the inner region of the pipe to minimize the adherence and growth of biofilms. Lubricant-infused surfaces has been one such interesting material for anti-biofouling applications in which their slippery property promotes repellence to many liquids and thus prevents bacterial adherence. Textured and porous films are suitable substrate candidates to infuse and contain the lubricant. However, there is little investigation in utilizing a nanoparticulate thin film as the substrate material for lubricant infusion. A nanoparticulate film has high porosity within the structure which can promote greater lubricant infusion and retention. The implementation as a thin film structure aids to reduce material consumption and cost. In our study, we utilized a well-studied nanoporous thin film fabricated via layer-by-layer assembly of polycations and colloid silica and then calcination for greater stability. The film was further functionalized to promote fluorinated groups and improve affinity with a fluorinated lubricant. The pristine nanoporous film was characterized to determine its morphology, thickness, wettability, and porosity. The lubricant-infused film was then tested for its lubricant layer stability upon various washing conditions and its performance against bacterial biofilm adherence as a result of its slippery property. Overall, the modified silica nanoparticulate thin film demonstrated potential as a base substrate for lubricant-infused surface fabrication that repelled against ambient aqueous solvents and as an anti-biofouling coating that demonstrated low biofilm coverage and colony forming unit values. Further optimization to improve lubricant retention or incorporation of a secondary function can aid in developing better coatings for biofilm mitigation.

It is difficult for any marine engineering equipment to avoid the impact of biofouling. Especially, for engineering equipment made of titanium with a high biocompatibility, biofouling is a thorny problem. The outstanding antibiofouling properties of the slippery liquid-infused porous surfaces (SLIPSs) and the grafted polydimethylsiloxane (gPDMS) brush surfaces have attracted the attention of researchers. However, the durability and stability of the conventional SLIPSs and the wear resistance of gPDMS are insufficient and should be improved. In this work, PDMS molecule brushes were grafted onto a micro-arc oxidized porous surface infused with a lubricant (silicone oil) to develop a grafted SLIPS (gSLIPS) on a titanium alloy (TA2). The gPDMS molecule brushes have a stronger chemical affinity with silicone oil, which can preserve more lubricants to enhance the durability and stability of the SLIPS. Simultaneously, the infused lubricant in the micro-arc oxidized porous surface can improve the wear resistance of the grafted molecule brushes. Besides, the molecule brushes can further isolate the vulnerable titanium substrate from the biofouling microorganisms. By combining the advantages of the SLIPS and gPDMS, the gSLIPS has excellent stability, durability, and mechanical robustness. The gSLIPS possesses a better biofouling resistance than TA2 and gPDMS. For example, the coverage of Chlorella on the gSLIPS is 0.067% ± 0.022% after being immersed for 14 days, which reduces by 98.8 and 95.6% compared with those on TA2 and gPDMS, respectively. In addition, the gSLIPS also has excellent anti-protein property. Therefore, this method will help develop a more stable, durable, and mechanically robust super-slippery coating with excellent antibiofouling performance, which has great potential for the extensive titanium applications in marine engineering.
