“…As shown in Figure , GO exhibits four characteristic absorption peaks at 3417, 1633, 1070, and 1336 cm –1 , which can be attributed to the stretching vibration of O–H, CO, and C–O bonds and the bending vibration of O–H bonds, respectively . JGO exhibits two additional peaks at 2920 and 2847 cm –1 , which are ascribed to the C–H stretching vibration of the alkyl chain, thereby confirming the presence of dodecylamine …”

Great aqueous dispersibility, a large specific surface area, and high impermeability make graphene oxide (GO) the ideal candidate for a high-performance corrosion inhibitor. Numerous symmetrical modification methods have been reported to enhance the adsorption of GO on metal surfaces in various corrosive media. This work aims to investigate the enhancement and mechanism of unilateral hydrophobic modification on the corrosion inhibition performance of GO. In this study, amphiphilic Janus GO (JGO) was prepared by grafting hydrophobic alkyl chains on one side of GO, and its anticorrosion performance was evaluated via weight loss experiments and electrochemical tests. The results revealed that the corrosion inhibition efficiency for Q235 mild steel (MS) in a 1 M HCl aqueous solution of 25 ppm JGO (81.08%) was much higher than that of GO at the same concentration (22.12%). Furthermore, the Langmuir adsorption isotherm and computational study demonstrated that the synergistic effect of physical adsorption and chemical adsorption promoted the hydrophilic side of JGO close to the surface of the metal, and the dense protective layer was formed by the hydrophobic chains toward the corrosive medium, which effectively hindered the corrosion of MS by the acidic liquid. This study emphasizes the significant role of asymmetrically modified hydrophobic alkyl chains in improving the corrosion prevention performance of GO and provides a perspective for the structural design of GO-based corrosion inhibitors.

In order to improve the utilization of fracturing fluid and reduce the environmental pollution risk in large‐scale fracturing of oil reservoirs in Ordos Basin, a type of reusable surfactant fracturing fluid is developed. Its formula composition is 15 × 10−3 g/mL of the synthesized surfactant and 6 × 10−3 g/mL of composite acid. The synthesized surfactant is formed by using 13‐docosaenoic acid, 3‐dimethylaminopropylamine, sodium chloroacetate, and other raw materials. The dissolution time of the fracturing fluid is less than 1 min. Due to the reversible entanglement interactions between the surfactant micelles, it is a viscosity‐elastic fracturing fluid with good sand carrying capacity. It can remain basically unchanged after shearing. The surfactant fracturing fluid can be automatically broken to contact with the crude oil in the oil reservoir. The breaking time can be controlled within 100 min by adjusting the concentration of crude oil. After gel breaking, the viscosity is less than 2.9 mPa ∙ s and the residue content is less than 1.25 mg/L. The interfacial tension of oil and the breaking liquid is below 0.1 mN/m. Subsequently, the field application of the fracturing fluid in N190 oil well has been carried out successfully. The backflow fluid of the surfactant fracturing fluid is successfully reused three times, and the performance of the fracturing fluid prepared in the field is basically consistent with the results of laboratory experiments. The fracturing construction by using the developed surfactant fracturing fluid can achieve a good fracturing stimulation effect and save a large amount of water resources.
