“…This surface modication technique enables minimal background contamination, making it highly suitable for applications in high-throughput screening experiments or microarray-based immunoassays in the eld of biomedical engineering. 44 In addition to hydrophobic molecules, 45 hydrophilic ones have also been assembled into smooth and slippery lms. 46,47 The utilization of a hybrid monolayer of poly(ethylene glycol)functionalized silane offers notable advantages for the antifrosting treatment of heat exchangers that feature densely packed aluminum ns.…”

“…The third type of coating is the grafted polydimethylsiloxane (gPDMS) brush surface fabricated by grafting liquid-like polymer molecules onto the solid surfaces via covalent bonds. 28 The solid surface is grafted with one end of the polymer molecule, while the other end can freely twist and wiggle. Thus, this type of coating also possesses dynamic surfaces, similar to the SLIPSs.…”

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.

“…The existence of transparent coatings simultaneously possessing the wear resistance of glass and the flexibility of polymers is relatively rare and has only recently been recently reported. Typically, such coatings are created through the curing of silica/organic molecular hybrids, including ladder-like polysilsesquioxanes ,, and functional polyhedral oligomeric silsesquioxanes (POSS). − ,,, Although wear-resistant options may include fluorinated liquid polymers or poly(dimethylsiloxane) chemically bonded to rigid substrates like glass, − these rigid substrates lack the desired flexibility. Additionally, a liquid-like monolayer such as poly(dimethylsiloxane) does not provide the desired antismudge or ice-shedding properties when grafted onto a porous rather than a smooth substrate. − …”

The encapsulating film of current foldable smartphone touchscreens consists of a flexible, colorless polyimide substrate, layered stepwise with a top hard coat, an antireflection coat, and last with an outermost antifingerprint layer. A flexible polymer substrate is essential to overcoming the inherent bendability limitations of the hard coat. This study explores a different approach to encapsulating film fabrication. This method involves the infusion of GPOSS (octakis(3-glycidyloxypropyl)silsesquioxane), GPOSS-FC6 (GPOSS with a perfluorinated hexyl group), and a cationic ring-opening initiator into electrospun nylon nanofiber mat pores and subsequently photocuring the GPOSS mixture to create a composite. The resulting film is transparent, omniphobic, and remarkably flexible. A 40 μm thick free-standing composite film alone can endure over 1000 bending cycles with a 1 mm radius without cracking. Additionally, it exhibits superior wear resistance by withstanding hundreds of steel wool abrasions, surpassing that of a cured neat F-GPOSS hard coating. This study highlights the remarkable reinforcing effect of electrospun nanofibers on hard materials, enhancing simultaneously the normally exclusive properties: flexibility and abrasion resistance. The reported material should find applications in various fields beyond foldable touchscreens.
