“…Peaks at 3330 cm −1 and 1620 cm −1 are ascribed to stretching and bending vibrations in O–H bonds, respectively 39 . The –CH–, –CH 2 –, and –CH 3 – asymmetry and symmetry vibrations are ascribed to the two peaks at 2936 cm −1 and 2830 cm −1 40 , 41 . The peak at 1640 cm −1 represents the C=C double bonds in the polycyclic aromatic graphene ring.…”

In this work, Ni and Ni-graphene, Ni-G, films were electrodeposited on copper substrate by potentiostatic deposition. To achieve superhydrophobicity, myristic acid, MA, was used to modify the surface of the electrodeposited coatings. The manufactured Ni film modified with myristic acid, Ni-MA, and the Ni-G film modified with myristic acid, Ni-G-MA, show excellent superhydrophobic, SHP, properties with a water contact angle of 159° and 162°, respectively. The surface morphology of the prepared SHP films was investigated using a Scanning Electron Microscope, and the results revealed micro-nano structures in both Ni-MA and Ni-G-MA films. The Fourier Transform Infrared Spectrophotometer data showed that the Ni-MA and Ni-G-MA films were successfully grafted on the copper metal. The Ni-G-MA film possessed higher chemical stability and mechanical abrasion resistance than Ni-MA. The Ni-MA and Ni-G-MA films exhibit long-term durability in the outdoor environment for more than four months. The potentiodynamic polarization and electrochemical impedance spectroscopy results demonstrated that the SHP films on the copper substrate exhibit remarkable corrosion resistance in 0.5 M NaCl.

“…The FTIR graph of BC displays several peaks that may be attributed to the presence of diverse functional groups. The broad peak observed at 3240 cm −1 is indicative of O-H stretching vibrations, while the two small peaks at 2856 cm −1 and 2922 cm −1 correspond to C-H stretching vibrations [37]. The sharp peak at 1590 cm −1 can be attributed to The existence of these functional groups provides evidence that nickel has been effectively incorporated into the biochar.…”

Researchers are looking at improved oil/water separation techniques due to the industry's struggles with separating oily wastewater discharge. One promising approach is to use superhydrophobic, SHP, membranes to separate oil from oily wastewater. In this study, we developed SHP textile fabric based on biochar, BC. The BC was synthesized from banana leaves by pyrolysis and then modified with nickel metal to produce Ni@BC. The textile fabric, TF, was submersed in an ethanolic solution of Ni@BC and stearic acid to produce the SHP coating. The Ni@BC was utilized to enhance the surface roughness of the pristine TF, and stearic acid was utilized to lower its surface energy. The surface morphology of the pristine and modified TF was studied by scanning electron microscope, SEM. The SEM results show that the modified TF shows a micro-nano structure. The Fourier transform infrared spectroscopy and energy-dispersive X-ray spectroscopy techniques confirmed the structure of Ni@BC and the grafting of both stearic acid and Ni@BC to the TF. The wettability results demonstrated that the prepared modified TF had a high degree of superhydrophobicity, with high water contact angle of 161° and a low water sliding angle of 1o. The modified TF showed excellent oil/water separation performance, with a separation efficiency of 99.9%. The oil absorption capacity of the TF was also high, with a capacity of 303 g/g for silicone oil, and it also has a high flux rate. The modified TF was also found to be mechanically and chemically stable, with no significant degradation after 10 cycles of use. The results of this study demonstrate that the biochar-based SHP TF is a promising material for oil/water separation.

“…4. The spectrum of pristine textile fabric displays a peak at 3430 cm −1 attributed to the N-H stretch of secondary amide and the two peaks at 2912 cm −1 and 2965 cm −1 , assigned to the -CH 2 -asymmetry and symmetry vibration 76 . The peak at 1715 cm −1 is attributed to the C=O stretch, and the peak at 1409 cm −1 is caused by the bending vibration of C-H.…”

In response to the industry's difficulty in properly separating oily wastewater discharge, researchers are investigating enhanced oil/water separation materials. In this work, a cost-effective and environmentally friendly superhydrophobic textile fabric was fabricated for effective oil–water mixture and emulsion separation. A biological metal–organic framework consisting of copper as a core metal and aspartic acid as a linker (Cu-Asp MOF) was used to improve the surface roughness of the pristine textile fabric, and stearic acid was used to lower its surface energy. The thermal gravimetric analysis investigated the prepared Cu-Asp MOF's thermal stability. X-ray spectroscopy and Fourier-transform infrared spectroscopy studied the crystal orientation and chemical composition of the Cu-Asp MOF, Cu-Asp MOF@SA, pristine textile fabric, and superhydrophobic textile fabric, respectively. The surface morphology of the pristine and modified textile fabric was studied by scanning electron microscope. The wettability results showed that the prepared superhydrophobic textile fabric has a water contact angle of 158° ± 1.3 and water sliding angle of 2° ± 0.2°. The prepared superhydrophobic textile fabric showed excellent oil–water mixture and emulsion separation performance, oil absorption capacity, chemical stability, mechanical abrasion resistance, and a high flux rate. These outstanding characteristics of the prepared superhydrophobic textile fabric greatly increase the possibility for practical applications.
