Novel super-hydrophobic poly(aryl ether ketone) (PAEK) membranes have been firstly prepared by modifying ordinary PAEK into hexafluorbisphenol A-PAEK through traditional nucleophilic condensation polymerization and subsequently simple electrospraying technique. With the solution concentration increased, the micromorphology exhibited nanofibers, nanofiber with spindles, 3D network with microspheres embedded, microspheres and dense films, successively. The static water contact angle increased from 99° to 155°, while the sliding angle from 1.3° to 6.8° (±1°), in which the 3D network presented the strongest super-hydrophobicity. After 200 h of water flushing, the rough surface structure and super-hydrophobicity of the membranes were well retained. Moreover, the membrane exhibited wonderful self-cleaning property, oil/water separation property, and stability due to the hierarchical micro/nanostructures. This work provides a new route for the creation of super-hydrophobic high performance engineering plastic fabrics with the potential values in large-scale application of filtration, oil/water separation, and antifouling.

“…Therefore, a number of researchers have developed various methods to fabricate functional engineering materials with superwetting performance for oil/water separation. Inspired by lotus leaf, many researchers have prepared massive superhydrophobic/superoleophilic materials [8][9][10][11][12][13][14] for oil/water separation or 'oil-removing' that enable oil permeation but prevent water penetration. Nevertheless, 'oil-removing' types of materials are easily fouled with oil of high viscosity.…”

BACKGROUND Recently, some smart superwetting materials with switchable wettability have attracted great interest due to their ability to controllably separate oil/water mixtures. However, the fabrication of most smart materials requires complex procedures and precious chemical reagents for surface modification, limiting large‐scale engineering applications of the fabricated smart surface. RESULTS In this study, a silver surface was prepared by extremely simple displacement deposition on copper mesh. The silver‐coated mesh exhibits superhydrophobicity and superoleophilicity after heating treatment, which allows oil to permeate while blocking water. Interestingly, the heated silver‐coated mesh gains superhydrophilic and underwater superoleophobic properties after UV irradiation, which allows water to permeate but prevents oil. As a consequence, the as‐fabricated mesh is capable of achieving two completely different oil/water separation processes. In addition, the silver‐coated mesh shows excellent environmental stability under a series of harsh conditions. CONCLUSION A novel smart engineering material with UV‐induced switchable wettability was successfully fabricated. In view of the rapid and simple fabrication approach, it is envisaged that this work will provide a promising prospect of large‐scale production in smart oil/water separation materials. © 2017 Society of Chemical Industry

Micro- and nanoporous materials capable of absorbing solvents and oils reversibly: the state of the art

et al. 2016

Treatment of petroleum spills and organic solvent pollution in general is an important issue; several techniques are under development to remove oil from water. The use of absorbents is one of the most common techniques to tackle this problem. These absorbents can be classified based on their characteristics of recyclability into irreversible and reversible ones. In this review, we discuss the application of several materials as oil absorbents, according to their classification and characteristics such as hydrophobicity, surface area and oil absorption capacity. Also, the fabrication methods for some materials are presented and analyzed.
