“…Eqn (5) represents the reaction, which takes place a little after etching. During this interval, the deposition reaction of Ag + solution with the copper substrate results in the formation of Ag 0 particles on the copper substrate surface, which is designated in eqn (6). Eventually, the CuO and AgO formed during the chemical reactions due to thermal annealing are represented in eqn ( 7) and ( 8), also supported by XRD.…”

“…It has been practically observed and believed that the greater the value of E corr and the lower the I corr , then anti-corrosion phenomena will be higher. 6 The efficiency of corrosion resistance of the non-coated and coated copper alloy was calculated by following the expression given below.where ‘ E ’ is efficiency, and R b and R c are the anti-corrosion resistance of bare copper alloy and Ag-NPs@SHS coated on the copper alloy. Hence, the corrosion resistance ( E ) of the non-coated copper alloy was calculated at 34.927%, whereas the anti-corrosion efficiency of a coated copper alloy was 201.199%.…”

“…The superhydrophobic surface has engaged the attention of researchers in recent decades due to its numerous applications, such as corrosion resistance, 1 self-cleaning, 2 anti-icing, 3 anti-fogging, 4 oil/water separation, 5 anti-bacterial, 6 catalytic reduction, 7 drag-reduction, 8 anti-biofouling, 9 super buoyancy, 10 photodegradation, 11 drug delivery and so on. 12 A surface with a static water contact angle greater than 150° and a sliding angle less than 10° is said to be a superhydrophobic surface (SHS).…”

Zinc oxide (ZnO)‐based composites are among the semiconductor photocatalytic materials that exhibit promising research opportunities in the fields of optical, biomedical, and environmental materials because of their excellent physical stability, biocompatibility, low cost, and ease of fabrication. This article discusses the fabrication and use of ZnO‐based composites with excellent catalytic activity. Here, the various combinations of sol‐gel ZnO coatings were prepared using the spin coating technique, and characterized by 3D laser profilometry, UV–visible spectroscopy, scanning electron microscopy (SEM). To determine the main functional groups, present in the prepared polymeric film, an FTIR investigation was conducted. The inclusion of Aloe vera with PF‐127 in the ZnO lattice is confirmed by the structural study of the X‐ray diffraction (XRD) pattern of Z‐PS, ZAL‐PS, and ZALPF‐PS, which showed a hexagonal wurtzite crystal structure and increasing in the peak position. The variation in strcuture and bandgap play major role in the enhancement of photocatalytic and antibacterial activity with ZALPF‐PS as compared to ZAL‐PS and Z‐PS. In contrast, water contact angle analysis reveals that the polymeric coating changes the surface roughness while simultaneously increasing the surface nonwettability. The prepared samples are also shown to be more resistant to Escherichia coli and Pseudomonas aeruginosa than standard antibiotics. This occurred because photocatalytic activity and superhydrophobic contact work together as a synergistic antibacterial mechanism. Furthermore, the nonwettable cotton substrate was also prepared, and their roughness behavior examined, which exhibited superhydrophobic performance against water, milk, coke, and coffee, which can be useful for medical purposes.
