“…There are many kinds of operation methods in the coating method, including blade coating, 33 and spray coating. 34 Although the coating method is simple to operate, it is also necessary to pay attention to the flatness and uniformity of the coating surface, otherwise it will affect the quality and performance of the final product. As a traditional coating method, the application of blade coating in various fields is more common.…”

“…The coating method, as the name suggests, is a method of covering a substrate (such as fabric, paper, and film) with coatings (such as paste polymers, molten polymers, and solution polymers) to produce composite materials. There are many kinds of operation methods in the coating method, including blade coating, 33 and spray coating 34 . Although the coating method is simple to operate, it is also necessary to pay attention to the flatness and uniformity of the coating surface, otherwise it will affect the quality and performance of the final product.…”

With the continuous development of the industry, oil spill accidents occur frequently. Oil/water separation materials are considered to be a major choice for the treatment of oily wastewater due to their flexible operation and low cost. Cotton fabrics are low‐cost and environmentally friendly, which are used as substrates to prepare oil/water separation materials with quite competitive in the market. A large number of oil/water separation cotton fabrics with excellent properties have been frequently reported in recent decades. On the other hand, since the service life of these oil/water separation cotton fabrics is closely related to the thin layer covered on the surface, so in order to improve the practical applicability, substances such as dopamine and plant polyphenols that improve the adhesion of the thin layer to the surface of the material are introduced into the preparation process of these materials. On this basis, the research progress of super‐hydrophobic cotton fabrics, super‐hydrophilic/underwater super‐oleophobic cotton fabrics, super durable oil/water separation cotton fabrics and intelligent response to oil/water separation fabric in recent years are reviewed, as well as their applications in the field of oil/water separation.

Bio-inspired macrostructure array (MAA, size: submillimeter to millimeter scale) materials with special wettability (MAAMs-SW) have attracted considerable attention due to their outstanding performance in many fields, such as oil repellency, liquid/droplet manipulation, anti-icing, heat transfer, water collection, and oil−water separation. In this review, we mainly focus on recent developments in the theory, design, fabrication, and application of bio-inspired MAAMs-SW. First, we briefly introduce the basic theory of special wettability. Afterwards, we discuss representative structures and corresponding functions of some biological surfaces. Then, we summarize fabrication methods of special wetting MAAs from the three categories of additive manufacturing, subtractive manufacturing, and formative manufacturing, including 3D printing, laser etching, wire electrical discharge machining, micro-mechanical cutting machining, electrochemical machining, template method, and imprinting method. In addition, we demonstrate the applications of these MAAMs-SW. Lastly, the challenges and directions of future research on bio-inspired MAAMs-SW are briefly addressed.

“…21 The first method is dipping the 3D-PMs with low-surface-energy materials, which is commonly used for aerogels, commercial sponges, and metal-base foams (e.g., cellulose aerogel, chitosan aerogel, polyurethane (PU), melamine sponges (MS), and Cu foam). [22][23][24][25][26] The commonly used low-surface-energy materials include poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), 1H,1H,2H,2H-perfluorodecyltriethoxysilane, perfluoropolyether (PFPE), and fluoroethylene vinyl ether (FEVE). [27][28][29][30] These 3D-PMs exhibit superior efficiency and recyclability in the cleanup of oil spill due to their low density, large surface area and high porosity.…”
