“…One of the major drawbacks to the dip-coating technique is the amount of solvent needed, causing considerable waste. Depending on the scale and compatibility of the substrate to the coating method, spray-coating can be easier and more efficient than spin- or dip-coating [ 21 , 54 , 59 , 60 , 61 ]. Furthermore, using the spray-coating technique, if an SH surface is damaged (for e.g., because of surface abrasion), it can be repaired by local spraying of the coating solution.…”

Nature has proven to be a valuable resource in inspiring the development of novel technologies. The field of biomimetics emerged centuries ago as scientists sought to understand the fundamental science behind the extraordinary properties of organisms in nature and applied the new science to mimic a desired property using various materials. Through evolution, living organisms have developed specialized surface coatings and chemistries with extraordinary properties such as the superhydrophobicity, which has been exploited to maintain structural integrity and for survival in harsh environments. The Lotus leaf is one of many examples which has inspired the fabrication of superhydrophobic surfaces. In this review, the fundamental science, supported by rigorous derivations from a thermodynamic perspective, is presented to explain the origin of superhydrophobicity. Based on theory, the interplay between surface morphology and chemistry is shown to influence surface wetting properties of materials. Various fabrication techniques to create superhydrophobic surfaces are also presented along with the corresponding advantages and/or disadvantages. Recent advances in the characterization techniques used to quantify the superhydrophobicity of surfaces is presented with respect to accuracy and sensitivity of the measurements. Challenges associated with the fabrication and characterization of superhydrophobic surfaces are also discussed.

“…The introduction of dispersants and flocculants into the water system poses a significant threat to marine microorganisms due to their inherent toxicity, resulting in severe ecological damage. 11 In recent years, with the development of membrane separation technology, membrane separation technology is considered to be an ideal and reliable technology for oily wastewater treatment because of its high separation efficiency, no secondary pollution, easy operation, and high separation efficiency 10,12,13 The types of oil-water separation membrane substrates are mainly including metal mesh, 14 non-solvent induced phase separation (NIPS) membranes, 15 and electrostatic spinning membranes. 16 Significant progress has been made in the design of micro-nano structures on the surface of metal mesh surfaces to change the composition and the surface energy.…”

“…In practical life, oil/water emulsions usually contain surfactants, the traditional separation materials cannot be demulsified before oil-water separation progress. 14,17 NIPS is one of the main techniques for the preparation of porous membranes. The concentration of the polymer, the amount and type of additives, the composition and the temperature of coagulation both are the main factors affecting the porous membrane formation.…”

Superhydrophobic materials have been used for the treatment of oily wastewater due to their selective absorption properties. However, many of the reported methods for creating superhydrophobic surfaces lack the feasibility for large-scale production due to the use of non-environmentally friendly chemicals or the involvement of complicated fabrication steps. In this study, we report a simple, green, and rapid process for fabricating superhydrophobic polyacrylonitrile (PAN) nonwoven fabric (NWF) for the separation of oil/water mixtures via adsorption and filtration strategies. PAN NWF was functionalized with iron hydroxide nanoparticles, which endowed the modified fabric with increased surface roughness and hydrophobic property. In the next step, the superhydrophobicity was attained by creating a multiscale hierarchical surface roughness and lowering the surface energy via an in situ deposition of the iron palmitate complex nano/ microparticles. The resulting superhydrophobic PAN NWF exhibited high chemical stability in corrosive environments and excellent mechanical durability as revealed from the sandpaper abrasion and tape peeling tests. The superhydrophobic NWF showed good oil absorption capacity, high permeation flux, high separation efficiency, and stable performance for 20 separation cycles. The excellent durability, recyclability, and long-term separation performance are expected to enable the application of the modified fabric for water−oil separation in harsh environments.
