“…With the rapid development of industrialization and the improvement of oilfield production technology, oil-bearing wastewater and organic wastewater have been continuously discharged into water bodies, causing serious environmental pollution and resource waste (Cao et al, 2019;Baig et al, 2022a;Kong et al, 2022). Among them, compared with conventional wastewater, polymer-containing wastewater in oilfield has complex composition and high emulsification stability (Liu, 2021;Qiao et al, 2022;Yu et al, 2022). The existing treatment technology is very limited, which makes the separation effect of oil and water unsatisfactory (Li et al, 2021).…”

At present, the application prospect of superhydrophobic materials in oil-water separation, an-tibacterial and other aspects have attracted more and more attention. However, preparing a simple and low-cost superhydrophobic material remains a challenge. Using acetone as solvent, candle soot, silver/silica nanoparticles and polydimethylsiloxane were uniformly mixed to form a mixed solution, and the superhydrophobic sponge was successfully prepared by spraying method. The results show that the superhydrophobic sponge has high water contact Angle (162°) and excellent oil-water separation efficiency, which can realize effective treatment of polymerized wastewater. In addition, the superhydrophobic sponge showed better antibacterial properties on the surface of Escherichia coli and Staphylococcus aureus. In this work, a simple way to prepare superhydro-phobic oil-water separation material is proposed. The preparation process is green, the material is easy to obtain, and it is expected to be widely used in practical production.

In polymer flooding, the residual polymer in the produced fluid can increase the stability of crude oil emulsion, thereby negatively affecting the demulsification process. Therefore, a polymer that has no effect on the stability of crude oil emulsion is required. Herein, a polymerizable monomer with a demulsification function (MD) was synthesized and then copolymerized with acrylamide, acrylic acid, and 2‐acrylamide‐2‐methylpropane sulfonic acid to prepare a novel copolymer (self‐demulsifying polymer, PDM). The dissolution time, solution viscosity, shear resistance, static adsorption on quartz sand, and the effect on the crude oil emulsion stability of PDM were compared with those of regular polyacrylamide (PAM). Experimental results showed that owing to the steric hindrance effect of MD, the molecular weight of PDM was lower than that of PAM. Both polymers exhibited satisfactory solubility, solution viscosity, shear resistance, and static adsorption, which can meet the requirements of polymer for use in oil displacement. However, in contrast to PAM, PDM had no negative effect on the crude oil emulsion stability. This study provides a new solution to the problem of increased crude oil emulsion stability in polymer flooding.
