“…The modified membranes could be used for continuous high-pressure oil/water separation while maintaining an extremely low water content of the filtrate (100.7 ppm at 500 mL), and were successful in separating oil/water mixtures with wide-ranging oil/water ratios. The coated surface exhibits an excellent chemical resistance compared to the wettability-modification literatures 41,42 , and does not exhibit any deterioration of wettability even in chemically severe environments, such as strongly acidic, alkaline, or saline conditions. The superhydrophobic nanostructured membranes capable of separating oil/water mixtures in these harsh environments have considerable potential for a wide range of novel applications.…”

We report a robust and continuous oil/water separation with nanostructured glass microfiber (GMF) membranes modified by oxygen plasma treatment and self-assembled monolayer coating with vertical polymerization. The modified GMF membrane had a nanostructured surface and showed excellent superhydrophobicity. With an appropriate membrane thickness, a high water intrusion pressure (< 62.7 kPa) was achieved for continuous pressure-driven separation of oil/water mixtures with high flux (< 4418 L h−1 m−2) and high oil purity (> 99%). Under simulated industrial conditions, the modified GMF membrane exhibited robust chemical stability against strong acidic/alkaline solutions and corrosive environments. The proposed superhydrophobic composite coating technique is simple, low cost, environmentally friendly, and suitable for the mass production of scalable three-dimensional surfaces. Moreover, its stability and customizable functionality offers considerable potential for a wide range of novel applications.

“…[42][43][44][45][46][47][48][49][50] The hydroxyl groups on anhydroglucose units make cellulose suitable for a variety of physical or chemical modifications. [51][52][53][54][55][56][57][58][59][60] Especially, graft polymerization of various monomers on the cellulose backbone by atom transfer radical polymerization (ATRP) in a living/controllable way is expected to produce functional materials, which could combine the advantage of synthetic polymer and natural polymer properties. [54,[61][62][63] Therefore, it is meaningful to graft catechol-bearing monomers onto cellulose to make biocompatible adhesives with strong mechanical strength and water resistance through ATRP.…”

Numerous traditional adhesives have good adhesion in dry environments. However, non-environmental-friendliness and poor water resistance largely limit their practical applications. To prepare biocompatible adhesives with strong water resistance and adhesion strength, in this paper, catechol-functionalized cellulose-based adhesive polymers are synthesized by grafting N-(3,4-dihydroxyphenethyl)methacrylamide and methyl methacrylate onto cellulose chain through atom transfer radical polymerization (ATRP). The successful synthesis of the catechol-functionalized cellulose-based adhesive polymers is confirmed by FTIR and 1 H NMR. The different characteristics of the adhesive polymers, such as thermal stability, swelling ratio, biocompatibility, and adhesion strength are investigated. Strong water resistance on various substrates is realized in underwater environment for the catechol-functionalized cellulose-based adhesive with addition of Fe 3+ . The adhesion strength and thermal stability are enhanced when the catechol content is increased. The adhesive with catechol content of 25.4% shows the adhesion strength of 0.45 MPa for iron substrate in underwater environment. In addition, the adhesive with addition of Fe 3+ exhibits excellent adhesion in dry environment, with maximum adhesion strength of 3.50 MPa for iron substrate. The cell culture test shows that the adhesive polymers have excellent biocompatibility. The biocompatible adhesives with strong water resistance have potential application in electronic, wood, and building fields.

“…Since Jiang et al [6] innovatively proposed a straightforward, rapid, and economical method for the construction of steel mesh film with superhydrophobic/superhydrophilic coatings for oil/water separation, various superhydrophobic substrates have gained attention for their potential application in oil/water separation [7,8,9,10,11,12,13,14]. The common oil/water separation materials such as stainless steel [15,16,17], strainer [18,19,20,21], filter paper [22,23,24,25], foam polyurethane [26,27,28,29], fabrics [30,31,32,33,34,35,36] and aerogels [37,38,39] have been widely studied in recent years. There still exist limitations such as low absorption capacities or environmental incompatibility or complicated preparation process.…”

In this paper, we present a facile and efficient strategy for the fabrication of magnetic, durable, and superhydrophobic cotton for oil/water separation. The superhydrophobic cotton functionalized with Fe3O4 magnetic nanoparticles was prepared via the in situ coprecipitation of Fe2+/Fe3+ ions under ammonia solution on cotton fabrics using polyvinylpyrrolidone (PVP) as a coupling agent and hydrophobic treatment with tridecafluorooctyl triethoxysilane (FAS) in sequence. The as-prepared cotton demonstrated excellent superhydrophobicity with a water contact angle of 155.6° ± 1.2° and good magnetic responsiveness. Under the control of the external magnetic field, the cotton fabrics could be easily controlled to absorb the oil from water as oil absorbents, showing high oil/water separation efficiency, even in hot water. Moreover, the cotton demonstrated remarkable mechanical durable properties, being strongly friction-resistant against sandpaper and finger wipe, while maintaining its water repellency. This study developed a novel and efficient strategy for the construction of magnetic, durable, and superhydrophobic biomass-based adsorbent for oil/water separation, which can be easily scaled up for practical oil absorption.
