“…TOS is one of the alkoxide organosilanes with four ethyl ester side chains and frequently used for hydrophobic coating. 16 The simple dip-coating method was applied to prepare TOS-coated Zn anodes in the same manner as the APTES-coating. As shown in Figures 3a and S28, the hydrophobic artificial SEI layer was conformally covered on Zn anodes with approximately 500 nm thickness after thermalcuring.…”

“…To verify the importance of surface hydrophilicity, we developed a hydrophobic artificial SEI layer on the surface of Zn using triethoxy(octyl)silane (TOS) instead of APTES. TOS is one of the alkoxide organosilanes with four ethyl ester side chains and frequently used for hydrophobic coating . The simple dip-coating method was applied to prepare TOS-coated Zn anodes in the same manner as the APTES-coating.…”

Chronic problems of zinc (Zn) metal anodes, such as notorious zinc dendrite growth and continuous side and corrosion reactions, hamper the commercialization of aqueous zinc-ion batteries (ZIBs). Herein, we have demonstrated the significance of surface properties of Zn anodes for suppressing parasitic side reactions and zinc dendrite growth. On the basis of the findings, we have successfully stabilized Zn anodes by building a thin and hydrophilic artificial solid electrolyte interphase (SEI) layer via a simple dip-coating method. The artificial SEI layer effectively inhibits the parasitic side reactions and guarantees uniform Zn stripping/plating for dendrite-free Zn anodes. As a result, durable cycle stability (3000 cycles at 1 A g −1 ) is achieved. More importantly, the artificial SEI layer is easily adapted for enlarged Zn anodes (176 cm 2 ) and highly stable cell operation is observed. This strategy can provide a more practical path and significant advances for developing aqueous ZIBs for large-scale ESSs.

“…In this work, Triethoxy-Octylsilane (OCTS) surfaces were prepared from an isopropyl orthotitanate sol to take advantage of the hydrophobic character exhibited by densely packed alkane surfaces [34,35]. Two different viruses of medical relevance, human adenovirus type 5 (Ad5) and human reovirus, were adsorbed on OCTS surfaces to characterize mechanical properties such as deformability, elasticity or breakage of the viral capsid [36][37][38].…”
