“…Some previous studies have also reported that more than 99% of bacteria can be removed under the synergistic effect of photothermal bactericidal property and superhydrophobic performance. − The obtained resisted bacterial adhesion rate of the IR/laser/cones/G surface in this study is similar to these reports, suggesting that the synergistic effect of photothermal graphene and superhydrophobicity significantly improves the antibacterial performance of the IR/laser/cones/G surface. Furthermore, we conducted a 20 times antimicrobial assay on the IR/laser/cones/G surface to evaluate its antibacterial stability (Figure S8 of the Supporting Information).…”

The presence of microorganisms on biomedical devices and food packaging surfaces poses an important threat to human health. Superhydrophobic surfaces, a powerful tool to combat pathogenic bacterial adhesion, are threatened by their poor robustness. As a supplement, photothermal bactericidal surfaces may be expected to kill adhered bacteria. Using copper mesh as a mask, we prepared a superhydrophobic surface with a homogeneous conical array. The surface shows synergistic antibacterial properties, including a superhydrophobic character against bacterial adhesion and photothermal bactericidal activity. As a result of the excellent liquid repellency, the surface could highly repel the adherence of bacteria after immersing in a bacterial suspension for 10 s (95%) and 1 h (57%). Photothermal graphene can easily eliminate most adhered bacteria during the subsequent treatment of near-infrared (NIR) radiation. After a self-cleaning wash, the deactivated bacteria were easily rinsed off the surface. Furthermore, this antibacterial surface exhibited an approximately 99.9% resisted bacterial adhesion rate regardless of planar and various uneven surfaces. The results offer promising advancement of an antibacterial surface combining both adhesion resistance and photothermal bactericidal activity in fighting microbial infections.

“…For example, Lin [42] reported a dual-functional superhydrophobic photothermal coating on glass by a chemical vapor deposition method, which was obtained by using candle soot (CS) and 1 H, 1 H, 2 H, 2 H-perfluorodecyltrimethoxysilane (PFDTMS) as row materials, coating exhibited superhydrophobic and great antibacterial and antibiofilm formation Performance. Chen [43] fabricated a superhydrophobic 316L stainlesssteel mesh by using perfluorooctanoic acid as low energy materials through an anodic oxidation method, the separation efficiency of various oils was above 95%, etc. However, these fluorine-containing materials are usually costly, complex fabrication process and existence secondary contamination [44].…”

Oil-water separation using special wettability materials has received much attention due to its low energy consumption and high separation efficiency. Herein, a fluorine-free superhydrophobic cotton fabric(PDMS/STA -coated cotton fabric) was successfully prepared by a simple impregnation method using hydroxyl-capped polydimethylsiloxane (PDMS-OH), tetraethoxysilane (TEOS) and stearic acid (STA) as precursors. The Investigation found that the cross-linking reactions between the hydroxyl groups form PDMS-OH, hydrolyzed TEOS made a strong interact of PDMS-OH and cotton fabric. Besides, a suitable roughness surface of coated cotton fabric was established by introducing STA due to its long chain-structure. The contact angle of this composite can reach 158.7°under optical condition due to its low surface energy and desired roughness. The oil/water separation efficiency of PDMS/STA-coated cotton fabric is higher than 90% even after 10 cycles of oil-water separation, the oil flux can reach 11862.42 L m-2 h-1. In addition, PDMS/STA-coated cotton fabric exhibits excellent chemical stability and durability under extreme conditions such as strong acid (HCl, pH=1~2) and alkali (NaOH, pH=13~14), the hydrophobicity of PDMS/STA-coated cotton fabric was decreased to 147° even after 350 cycles of abrasion testing.
