“…SSM not only has better processing performance but also better mechanical properties, is less expensive, and has better chemical stability than copper mesh. Tang et al 73 used a biomeralization strategy to prepare an underwater superoleophobic CaCO 3 mineral coating SSM with a micro/nano structure on the surface, and the underwater OCA was as high as 161°. CaCO 3 ‐SSM maintained OCAs above 154° in strong acid, alkali, and high salt solutions.…”

Special wettability fibrous materials have received a lot of attention because of their good connectivity, mechanical flexibility, large specific surface area, and ease of shape manipulation. Their outstanding performance paves the way toward efficient oil/water separation in a variety of environments and for separation requirements. This paper discusses the distinct advantages, challenges, and future research directions of various substrates for fibrous materials, such as nonwoven natural biomass fibers, fabrics, electrospinning fibers, metallic fibers, and inorganic nonmetallic fibers. The special wettability fibrous filter materials and fibrous adsorbents are summarized based on the different separation methods.The principles of preparation of various special wettabilities are introduced, and the unique advantages of fibrous adsorbents are emphasized. The preparation strategy of fibrous filter materials is discussed, as well as some representative work and research progress. The benefits, drawbacks, and research directions in terms of various materials are examined. This article emphasizes the pollution resistance of fibrous filter materials and the elasticity of fibrous adsorbents. Finally, the prospects in terms of the problems, challenges, and future development of special wettability fibrous materials used in oil/water separation are discussed.

“…The inner surface of the pipe possesses both oleophobicity and hydrophilicity, which is called the oleophobic and hydrophilic surface. The applications of oleophobic and hydrophilic surfaces mainly focus on oil–water separation, , antioil adhesion, and oil droplet transport. , Some scholars have conducted tentative research on the application of oleophobic and hydrophilic surfaces in heavy oil DR.…”

With the depletion of conventional light crude oil, heavy crude oil will occupy an increasing share of the energy structure in the 21st century. Heavy crude oil is characterized by an API gravity of 10 to 22.3 or a viscosity of 0.09 to 10 Pa·s. The flow of heavy crude oil in the pipeline is laminar in the higher viscosity range and turbulent in the lower viscosity range, and its flow resistance comes from the viscous force between the oil and the wall or the additional stress of turbulent flow. Hence, pipeline transportation of heavy crude oil is faced with a huge loss of frictional resistance, which means a reduction of the transportation efficiency. To decrease pump power consumption, improving the transportation efficiency of heavy crude oil pipelines is a key factor. In recent years, some biomimetic technologies that reduce the flow resistance of viscous oils have made new progress in improving their fluidity and have not yet been put into use in commercial pipelines. Therefore, it is important and appropriate to discuss the breakthrough achievements and progress made by researchers in the drag reduction (DR) of heavy crude oil and to summarize its advantages, disadvantages, and potential problems. This review discusses boundary layer control methods for heavy crude oil drag reduction. First, conventional DR technologies, such as polymers, surfactants, fiber suspensions, oil–water core annular flow (CAF) and oil–aqueous foam CAF, and potential DR technologies, including oleophobic surfaces, flexible walls, biomimetic microgrooves, and ferrofluid annular DR under magnetic confinement, are presented. Second, the mechanism of DR is investigated and summarized; the highlights and progress of the technology are reviewed, and new ideas to improve the existing DR technology are proposed. Finally, the challenges and prospects of DR are presented.

We present a biomimetic switchable MXene membrane for water treatment inspired by chloride ion transmembrane transport. The MXene membrane was modified with poly(2-diethylaminoethyl methacrylate), resulting in increased hydrophilicity and enlarged channels. The membrane exhibited a permeability of 4.42 × 104 L m–2 h–1 bar–1, surpassing conventional MXene membranes. The membrane also separated Methylene Blue positively charged at pH = 12 and Amido Black 10B negatively charged at pH = 2 with separation efficiency above 98%, thanks to controllable channel size and adjustable electrostatic interactions in response to pH or CO2. This research offers valuable insights into the design of pH-responsive membranes with adjustable selectivity, representing a significant advancement in smart filtration with versatile applications.
