The oily wastewater generated in the industrial field is adversely affecting the environment, while the current methods for oil–water separation are complex and costly. Therefore, it is significant to use low cost and environmentally friendly materials to prepare a smart responsive superhydrophobic coating for the effective separation of oil–water mixtures. In this paper, a fluorine-free copolymer with pH responsiveness was fabricated by a solution impregnation method, and it was compounded by silica nanoparticles/polydimethylsiloxane to prepare a superhydrophobic coating on the paper and cotton fabric. The prepared superhydrophobic coating remained in the superhydrophobic state after the alkali treatment, while it would be converted into the hydrophilic state after the acid treatment. Therefore, the pH-responsive superhydrophobic coating will be applied in controlled selective 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...

Superhydrophobicity is of interest for practical applications such as water repellency, self-cleaning, stain resistance, antibacterial properties, and oil−water separation. In this work, a superhydrophobic coating on cotton fabric is prepared by simple immersion in TiO 2 nanoparticles and perfluorodecyltriethoxysilane solution. Its antiwetting properties, surface morphology, and functionality are characterized. The cotton fabric shows superhydrophobicity with a water static contact angle of 169.3 ± 2.1°and tilt angle of 6.3 ± 2.0°. The coating is also characterized by performing stability tests, and it shows excellent mechanical durability, chemical stability, and thermal stability. Additionally, the water droplet dynamic on the coated surface is also studied. The coated cotton fabric exhibits excellent self-cleaning, stain resistance, rust stain resistance, anti-water absorption, and antibacterial properties. It can also be used in oil−water separation with a high separation efficiency and excellent reusability.
