“…In general, our self‐made polyHIPE microspheres@stainless steel meshes have outstanding permeation flux of no less than 187.5 L/(m 2 ·min) for oils. The best permeation flux towards ethyl acetate and carbon tetrachloride is more than 1500 L/(m 2 ·min), which is higher than most of reported metal mesh‐based separation films, 15,47–49 and similar to the reported work of Huang in Table 2 29 …”

“…Moreover, the water intrusion pressure of M1 is lower than that of M3, and so is the same for comparing M2 with M4, which is due to a large accumulation gap of P(St‐DVB) 300 rpm microspheres as previously mentioned. The maximum water intrusion pressure of these 12 self‐made separation films can reach 1568 Pa (M9 and M11), which is higher than those of reported metal mesh‐based separation films, 29 and close to stainless steel mesh with superhydrophobic copper film (Table 2). 46 From Figure 7b, it can be also seen that the water intrusion pressure of self‐made separation films can be readily tuned by changing the size, amount and composition of microspheres.…”

“…Most recently, attempting to use fluorine-free polymer materials for oil-water separation also indicated the demand for eco-friendly and sustainable strategies. Some polymers with low-surface energy, such as polydimethylsiloxane (PDMS), 25,26 polyhedral oligomeric silsesquioxane, 27 polybenzoxazine, 28 polyacrylate, 29 and crosslinked copolymers, 30 have been reported for preparation of superhydrophobic surface. For instance, Shuai et al prepared superhydrophobic PDMS-TiO 2 coated polyurethane sponge with the WCA of 154 by sol-gel growth of TiO 2 nanoparticles on surface for selective absorption of oil from water.…”

In this study, we report a new facile method to prepare fluorine-free superhydrophobic separation films by deposition of micron-sized hydrophobic polyhigh internal phase emulsion (polyHIPE) microspheres on stainless steel meshes. The so-called polyHIPE microspheres are polymer ones with interconnected porous structures, which are prepared by γ-ray radiation polymerization of (W/O HIPE)/W double emulsions stabilized by a single emulsifier 12-acryloyloxy-9-octadecenoic acid using a one-step emulsification in this work. The oil-water separation results show that our self-made hydrophobic meshes have excellent oil-water separation efficiency (about 99.5%), outstanding permeation flux (no less than 187.5 L/[m 2 Ámin] and the maximum value of 1850 L/[m 2 Ámin]). The oil flux of common organic solvents, water contact

“…The rapid development of economy in the world is accompanied by a massive daily discharge of industrial organic waste liquids and the disastrous leakage of offshore crude oil once in a while, which severely pollute the biological environment and endanger human health. With no doubt, formulating effective oil/water separation strategies has become a hot topic worldwide. − The large-scale applications of traditional oil/water separation technologies such as centrifugation, adsorption, and air flotation have been greatly limited due to high energy consumption, low separation efficiency, and complicated operation. , Oil/water separation membranes and coatings are functional materials with special wettability that have been extensively researched over the past few years. − To date, various commercial materials are used as coating substrates for oil/water separation, including cotton fabrics, 3D porous materials, various polymer membranes, filter papers, and meshes . The oil/water separation membranes based on metal meshes, especially copper meshes, have received extensive attention owing to their high mechanical strength and wide industrial applications with satisfactory recyclability. , …”

Facile and fluoride-free fabrication of high-throughput superhydrophobic materials to achieve efficient separation of oil/water mixtures is of great significance. A superhydrophobic copper mesh (SHCM) was synthesized by constructing copper hydroxide nanoneedles on a copper mesh via chemical oxidation followed by further modification with trichloromethylsilane. The band-shaped nanoneedles on the very top were interwoven to form a uniformly distributed array of silicone spots, resulting in a hierarchical surface structure. The synthesized SHCM possessed a static water contact angle (WCA) of up to 159°with good superoleophilic properties. The SHCM was applied for the separation of various oil/water mixtures, and the separation efficiency was up to 99.9% with extremely high oil fluxes of over 220 kL•m −2 h −1 . In addition, the excellent separation efficiencies and high throughputs of SHCM could be maintained with slightly lowered WCAs even after 80 separation cycles and a particle impact abrasion test. Using a self-designed netlike oil skimmer equipped with a SHCM, the floating oil on water could be easily collected. The SHCM synthesized in this study using a facial synthetic strategy has great potential in the application of actual oil/ water separation.

This oily wastewater has severe adverse effects on the environment, as previously witnessed during several oil spill accidents in the marine and terrestrial environments due to oil leakage from petroleum transport pipelines, storage tanks or transport facilities, and blowouts in oil wells. [3] The treatment of oily wastewater can be performed via numerous technologies such as adsorption, [4] dissolved air flotation, [5] coagulation, [6] gravity separation, [7] and biological treatment. [8] However, these methods have several limitations, such as low removal efficacy, high operational cost, high energy consumption, corrosion, and production of contaminated solid waste from spent adsorbents. [9] The rapid growth in separation technologies has resulted in various membranes that could overcome the shortcomings of other treatment methods. [10] Thus, membranes have become more desirable for oil/water separation for industrial applications because of their small footprint, environmental friendliness, cost-effectiveness, high productivity, low chemical consumption, automation capability, steady operation, and excellent separation efficiency. [11] Indeed, pore blockage or fouling remains among the major obstacles facing the membrane separation process since it decreases the flux, restricts the permeation rate, increases the energy consumption, and decreases the membrane lifetime. Therefore, substantial research efforts have been focused on enhancing the properties of membranes either via developing novel materials or introducing surface modifications for conventional membranes. [12,13] Although few reviews were published on oil/water separation membranes, they are either outdated or focused on a specific membrane type. This review features the most recent progress in membrane separation and its practical application in oil/water separation. It includes four sections that cover essential factors related to the advancement in membrane technologies are highlighted, including: 1) membrane properties and characterization for oily waste water separation; 2) the employed materials to fabricate membranes (i.e., metallic, organic, inorganic, and hybrid materials), 3) primary methods for designing membranes (i.e., mixed matrix nanocomposites and multilayers nanocomposites), and 4) membrane fabrication techniques and surface modification methods. Membrane Properties and CharacterizationThe main objective of the oil/water separation membrane is to achieve high separation efficiency and excellent performance.Recent advancements in separation and membrane technologies have shown a great potential in removing oil from wastewaters effectively. In addition, the capabilities have improved to fabricate membranes with tunable properties in terms of their wettability, permeability, antifouling, and mechanical properties that govern the treatment of oily wastewaters. Herein, authors have critically reviewed the literature on membrane technology for oil/water separation with a specific focus on: 1) membrane properties and characterization, 2) d...
