The novel functional superwettable materials for high-efficiency oil/water separation are urgently required due to oil pollution in water body caused by oil tanker accidents, seabed oil production, and oil from refineries and petrochemical plants. Here, the superhydrophobic and superoleophilic zeolitic imidazolate framework-L (ZIF-L) mesh with antimicrobial effect was successfully fabricated by in-situ growth, composed of vertically ZIF-L with micro-/nanodagger-like structure and exhibited the water contact angle of 155.4 ± 1.8 and the oil contact angle of 0 in air. Furthermore, ZIF-L was verified to have an excellent antimicrobial activity, which endowed ZIF-L mesh with good antimicrobial performance. ZIF-L mesh provided a permeation flux with 1.75 × 10 5 L m −2 hr −1 and 99.7% separation efficiency after 10 cycles operations for water mixtures with isooctane and presented optimal stability. Accordingly, the results demonstrated that ZIF-L as a new material shows an attractive applied promise for oil/water separation in industry.

“…Superhydrophobic surfaces with water repellency are usually defined as water contact angle (CA) greater than 150° and sliding angle (SA) lower than 10°, attracting much attention for their potential applications, such as anti‐icing,self‐cleaning, anticorrosion, oil–water separation, drag reduction, and so on. Many studies have proved that the combination of proper micro/nanoscale structures and low surface‐energy materials (fluoro or silane‐containing polymer) is essential to endow a surface with superhydrophobicity .…”

In this work, a flower clusters-like superhydrophobic surface was fabricated via an ultraviolet (UV) curable coating of octadecylamine (ODA) and vinyl-terminated polydimethylsiloxane (V-PDMS). ODA self-assembled into many flower clusters-like structures on the surface of the coating, increasing the roughness of the coating surface without additional nanoparticles. V-PDMS formed a highly crosslinked network under a UV lamp, which would be helpful for a robust superhydrophobic surface. The obtained PDMS/ODA fabric showed water contact angle of 161 and sliding angle of 5 . The durability of the superhydrophobic surface was tested by water impacting, tube brush scrubbing, knife scratching, hand twisting, finger pressing, tape adhesion, abrasion, continuous rinsing, and chemical conditions. The experimental results indicated that the superhydrophobic surface have good durability for long service life. Moreover, the PDMS/ODA fabric could selectively absorb oils from water with good separation performance. This work will provide a facile, low cost, and versatile method to prepare superhydrophobic surfaces, and enhance their efficiency of oil-water separation.

“…Generally, these superwetting separating films can be divided into two types. The first is the superhydrophobic/superoleophilic films that can filtrate oil from oil/water mixtures, for example, Teflon‐coated stainless steel mesh substrates, carbon‐nanotube sponges, and polydimethylsiloxiane (PDMS)‐coated nanowire membranes . The second type is films with superhydrophilicity/underwater superoleophobicity, such as hydrogel‐coated metal films, porous nitrocellulose membranes, and Cu(OH) 2 ‐coated copper mesh films, that can separate water from the mixture .…”

Inspired by the special asymmetric wettability and controllable permeation function of cell membranes, we report a Janus nanostructured copper mesh film with unidirectional water transportation ability. Water can permeate from the hydrophobic side to the hydrophilic side, but is retained in the opposite direction. Notably, based on this special unidirectional water permeation property, both heavy oil/water mixtures (ρ >ρ ) and light oil/water mixtures (ρ <ρ ) can be separated. Additionally, the film demonstrates high separation efficiency and good recyclability. This paper reports a new Janus film that achieved highly efficient oil/water separation based on smart control of the wettability of the film. It is believed to have the potential to be used in many practical applications, such as wastewater treatment and oil-spill cleanup.
