“…A higher E corr and smaller I corr on the polarization curves indicate that the tested samples have a better anticorrosive performance. 62 , 63 Figure S7c shows that, compared with ECP-40 and ECP-Ag-40, after modification by 1-hexadecanethiol, the E corr of ECP-Ag-SH-40 moved significantly in the positive direction. The I corr of ECP-Ag-SH-40 was also smaller than those of ECP-40 and ECP-Ag–40, which indicates that superhydrophobic treatment can inhibit ECP-Ag-SH-40 corrosion.…”

The functional design of paper-based material surfaces with renewable functions and environmentally friendly properties is prevalent nowadays. Herein, a superhydrophobic surface with a coral reef-like structure was prepared on filter paper by electroless copper plating, rapid silver nitrate etching, and facile 1-hexadecanethiol impregnation. After low-surface-energy thiol treatment, this unique coral reef-like structure surface showed excellent superhydrophobicity with a water contact angle of 163.8° and superoleophobicity with an oil contact angle of 0°, which could be used for oil–water separation and had a separation efficiency above 89.17% after 12 consecutive oil–water separations. Because the copper layer and silver nanostructure are both excellent conductive materials, the modified paper exhibited excellent electromagnetic shielding properties, and the electromagnetic interface shielding effectiveness exceeded 63 dB from 9 kHz to 1.5 GHz. The modified paper also had excellent self-cleaning properties and a better corrosion resistance. The unique three-dimensional interweaving structure between the cellulose fibers in the filter paper is fully utilized, and the substitution reaction between the silver ion and the copper coating produces a coral reef-like structure, which provides a new strategy for promoting the wide application of paper-based materials.

Friction is widespread in almost every field in the oil and gas industry, and it is accompanied by huge energy losses and potential safety hazards. To deal with a series of questions in this regard, biomimetic surfaces have been developed over the past decades to significantly reduce economic losses. Presently, biomimetic surface engineering on different scales has been successfully introduced into related fields of the oil and gas industry, such as drill bits and the inner surfaces of pipes. In this review, we focused on the most recent and promising efforts reported toward the application of a biomimetic surface in oil and gas fields, indicating the necessity and importance of establishing this disciplinary study. Regarding the oil and gas industry, we mainly analyzed and summarized some important research results into the following three aspects: (i) applications in reducing the wear of exploration production equipment and its components, (ii) separation and drag release technologies in oil/gas storage and transportation, and (iii) functional coatings used in oil and gas development in oceans and polar regions. Finally, based on an in-depth analysis of the development of biomimetic surface engineering in the fields of oil and gas, some conclusions and perspectives are also discussed. It is expected that biomimetic surface engineering can be used in oil and gas fields more widely and systematically, providing important contributions to green development in the near future.

“…Superhydrophobic surfaces have become a popular topic due to their application in oil/water separation [ 2 , 3 , 4 ], anti-corrosion [ 5 ], drag reduction [ 6 ], reproductive medicine and cryobiology [ 7 ] et al Superhydrophobic surfaces, characterized by high apparent contact angles (> 150°) and low contact angle hysteresis (the difference between the advancing and receding contact angles, which could lead to a low sliding angle), have tremendous practical applications, including self-cleaning and drag reduction. The non-wetting coatings could eliminate liquid food residue, avoiding the adhesion of viscous liquid to packaging material [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

Liquid food adhesion on containers has increased food waste and pollution, which could be effectively alleviated with a superhydrophobic surface. In this research, the superhydrophobic coating was fabricated with edible soybean wax on different substrates by a spraying method. The coated surface showed excellent superhydrophobicity due to its microstructure formed by self-roughening, which could repel a variety of viscous liquid food with the apparent contact angle of 159 ± 2°. The coated surface was still liquid-repellent after hot water immersion (45 °C), abrasion test with sandpaper, water impact, finger touch and immersion into yogurt. The liquid-repellent coating with soybean wax, which is natural and green, is promising for application in the food industry to reduce waste.
